     How to install HTML Purifier
 
-HTML Purifier is designed to run out of the box, so actually using the
-library is extremely easy.  (Although... if you were looking for a
-step-by-step installation GUI, you've downloaded the wrong software!)
-
-While the impatient can get going immediately with some of the sample
-code at the bottom of this library, it's well worth reading this entire
-document--most of the other documentation assumes that you are familiar
-with these contents.
+HTML Purifier is designed to run out of the box,  so actually using the library
+is extremely easy. (Although, if you were looking for a step-by-step
+installation GUI, you've come to the wrong place!)  The impatient can scroll
+down to the bottom of this INSTALL document to see the code, but you really
+should make sure a few things are properly done.
+
 
 
----------------------------------------------------------------------------
 1.  Compatibility
 
-HTML Purifier is PHP 5 only, and is actively tested from PHP 5.0.5 and
-up. It has no core dependencies with other libraries. PHP
-4 support was deprecated on December 31, 2007 with HTML Purifier 3.0.0.
+HTML Purifier works in both PHP 4 and PHP 5, from PHP 4.3.9 and up. It has no
+core dependencies with other libraries. (Whoopee!)
 
-These optional extensions can enhance the capabilities of HTML Purifier:
-
-    * iconv  : Converts text to and from non-UTF-8 encodings
-    * bcmath : Used for unit conversion and imagecrash protection
-    * tidy   : Used for pretty-printing HTML
+Optional extensions are iconv (usually installed) and tidy (also common).
+If you use UTF-8 and don't plan on pretty-printing HTML, you can get away with
+not having either of these extensions.
 
 
----------------------------------------------------------------------------
-2.  Reconnaissance
 
-A big plus of HTML Purifier is its inerrant support of standards, so
-your web-pages should be standards-compliant.  (They should also use
-semantic markup, but that's another issue altogether, one HTML Purifier
-cannot fix without reading your mind.)
+2.  Including the library
 
-HTML Purifier can process these doctypes:
+Simply use:
+
+    require_once '/path/to/library/HTMLPurifier.auto.php';
+
+...and you're good to go.  Since HTML Purifier's codebase is fairly
+large, I recommend only including HTML Purifier when you need it.
+
+If you don't like your include_path to be fiddled around with, simply set
+HTML Purifier's library/ directory to the include path yourself and then:
+
+    require_once 'HTMLPurifier.php';
+
+Only the contents in the library/ folder are necessary, so you can remove
+everything else when using HTML Purifier in a production environment.  
+
+
+
+3.  Preparing the proper output environment
+
+HTML Purifier is all about web-standards, so accordingly your webpages should
+be standards compliant.  HTML Purifier can deal with these doctypes:
 
 * XHTML 1.0 Transitional (default)
-* XHTML 1.0 Strict
 * HTML 4.01 Transitional
-* HTML 4.01 Strict
-* XHTML 1.1
 
 ...and these character encodings:
 
 * UTF-8 (default)
-* Any encoding iconv supports (with crippled internationalization support)
+* Any encoding iconv supports (support is crippled for i18n though)
 
-These defaults reflect what my choices would be if I were authoring an
-HTML document, however, what you choose depends on the nature of your
-codebase.  If you don't know what doctype you are using, you can determine
-the doctype from this identifier at the top of your source code:
+The defaults are there for a reason: they are best-practice choices that
+should not be changed lightly.  For those of you in the dark, you can determine
+the doctype from this code in your HTML documents:
 
     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
@@ -59,167 +64,35 @@ the doctype from this identifier at the top of your source code:

-If the character encoding declaration is missing, STOP NOW, and
-read 'docs/enduser-utf8.html' (web accessible at
-http://htmlpurifier.org/docs/enduser-utf8.html).  In fact, even if it is
-present, read this document anyway, as many websites specify their
-document's character encoding incorrectly.

+
+You may currently be vulnerable to XSS and other security threats, and HTML
+Purifier won't be able to fix that.
 
 
----------------------------------------------------------------------------
-3.  Including the library
 
-The procedure is quite simple:
-
-    require_once '/path/to/library/HTMLPurifier.auto.php';
-
-This will setup an autoloader, so the library's files are only included
-when you use them.
-
-Only the contents in the library/ folder are necessary, so you can remove
-everything else when using HTML Purifier in a production environment.
-
-If you installed HTML Purifier via PEAR, all you need to do is:
-
-    require_once 'HTMLPurifier.auto.php';
-
-Please note that the usual PEAR practice of including just the classes you
-want will not work with HTML Purifier's autoloading scheme.
-
-Advanced users, read on; other users can skip to section 4.
-
-Autoload compatibility
-----------------------
-
-    HTML Purifier attempts to be as smart as possible when registering an
-    autoloader, but there are some cases where you will need to change
-    your own code to accomodate HTML Purifier. These are those cases:
-
-    PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload
-        Because spl_autoload_register() doesn't exist in early versions
-        of PHP 5, HTML Purifier has no way of adding itself to the autoload
-        stack. Modify your __autoload function to test
-        HTMLPurifier_Bootstrap::autoload($class)
-
-        For example, suppose your autoload function looks like this:
-
-            function __autoload($class) {
-                require str_replace('_', '/', $class) . '.php';
-                return true;
-            }
-
-        A modified version with HTML Purifier would look like this:
-
-            function __autoload($class) {
-                if (HTMLPurifier_Bootstrap::autoload($class)) return true;
-                require str_replace('_', '/', $class) . '.php';
-                return true;
-            }
-
-        Note that there *is* some custom behavior in our autoloader; the
-        original autoloader in our example would work for 99% of the time,
-        but would fail when including language files.
-
-    AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED
-        spl_autoload_register() has the curious behavior of disabling
-        the existing __autoload() handler. Users need to explicitly
-        spl_autoload_register('__autoload'). Because we use SPL when it
-        is available, __autoload() will ALWAYS be disabled. If __autoload()
-        is declared before HTML Purifier is loaded, this is not a problem:
-        HTML Purifier will register the function for you. But if it is
-        declared afterwards, it will mysteriously not work. This
-        snippet of code (after your autoloader is defined) will fix it:
-
-            spl_autoload_register('__autoload')
-
-    Users should also be on guard if they use a version of PHP previous
-    to 5.1.2 without an autoloader--HTML Purifier will define __autoload()
-    for you, which can collide with an autoloader that was added by *you*
-    later.
-
-
-For better performance
-----------------------
-
-    Opcode caches, which greatly speed up PHP initialization for scripts
-    with large amounts of code (HTML Purifier included), don't like
-    autoloaders. We offer an include file that includes all of HTML Purifier's
-    files in one go in an opcode cache friendly manner:
-
-        // If /path/to/library isn't already in your include path, uncomment
-        // the below line:
-        // require '/path/to/library/HTMLPurifier.path.php';
-
-        require 'HTMLPurifier.includes.php';
-
-    Optional components still need to be included--you'll know if you try to
-    use a feature and you get a class doesn't exists error! The autoloader
-    can be used in conjunction with this approach to catch classes that are
-    missing. Simply add this afterwards:
-
-        require 'HTMLPurifier.autoload.php';
-
-Standalone version
-------------------
-
-    HTML Purifier has a standalone distribution; you can also generate
-    a standalone file from the full version by running the script
-    maintenance/generate-standalone.php . The standalone version has the
-    benefit of having most of its code in one file, so parsing is much
-    faster and the library is easier to manage.
-
-    If HTMLPurifier.standalone.php exists in the library directory, you
-    can use it like this:
-
-        require '/path/to/HTMLPurifier.standalone.php';
-
-    This is equivalent to including HTMLPurifier.includes.php, except that
-    the contents of standalone/ will be added to your path. To override this
-    behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can
-    be found (usually, this will be one directory up, the "true" library
-    directory in full distributions). Don't forget to set your path too!
-
-    The autoloader can be added to the end to ensure the classes are
-    loaded when necessary; otherwise you can manually include them.
-    To use the autoloader, use this:
-
-        require 'HTMLPurifier.autoload.php';
-
-For advanced users
-------------------
-
-    HTMLPurifier.auto.php performs a number of operations that can be done
-    individually. These are:
-
-        HTMLPurifier.path.php
-            Puts /path/to/library in the include path. For high performance,
-            this should be done in php.ini.
-
-        HTMLPurifier.autoload.php
-            Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class).
-
-    You can do these operations by yourself--in fact, you must modify your own
-    autoload handler if you are using a version of PHP earlier than PHP 5.1.2
-    (See "Autoload compatibility" above).
-

-5. Caching
 
-HTML Purifier generates some cache files (generally one or two) to speed up
-its execution. For maximum performance, make sure that
-library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver.
-
-If you are in the library/ folder of HTML Purifier, you can set the
-appropriate permissions using:
-
-    chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer
-
-If the above command doesn't work, you may need to assign write permissions
-to all. This may be necessary if your webserver runs as nobody, but is
-not recommended since it means any other user can write files in the
-directory. Use:
-
-    chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer
-
-You can also chmod files via your FTP client; this option
-is usually accessible by right clicking the corresponding directory and
-then selecting "chmod" or "file permissions".
-
-Starting with 2.0.1, HTML Purifier will generate friendly error messages
-that will tell you exactly what you have to chmod the directory to, if in doubt,
-follow its advice.
-
-If you are unable or unwilling to give write permissions to the cache
-directory, you can either disable the cache (and suffer a performance
-hit):
-
-    $config->set('Core.DefinitionCache', null);
-
-Or move the cache directory somewhere else (no trailing slash):
-
-    $config->set('Cache.SerializerPath', '/home/user/absolute/path');

-# APIs for ConfigSchema subsystem have substantially changed. See
-  docs/dev-config-bcbreaks.txt for details; in essence, anything that
-  had both namespace and directive now have a single unified key.
-# Some configuration directives were renamed, specifically:

-    %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping
-    %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope
-    %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl

-# The allowed values for class have been relaxed to allow all of CDATA for
-  doctypes that are not XHTML 1.1 or XHTML 2.0.  For old behavior, set
-  %Attr.ClassUseCDATA to false.
-# Instead of appending the content model to an old content model, a blank
-  element will replace the old content model.  You can use #SUPER to get
-  the old content model.
-! More robust support for name="" and id=""
-! HTMLPurifier_Config::inherit($config) allows you to inherit one
-  configuration, and have changes to that configuration be propagated
-  to all of its children.
-! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on
-  the name attribute when set. Use with care. Thanks Ian Cook for
-  sponsoring.
-! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty
-  tags that contain non-breaking spaces as well other whitespace. You
-  can also modify which tags should have &nbsp; maintained with
-  %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions.
-! Implement %Attr.AllowedClasses, which allows administrators to restrict
-  classes users can use to a specified finite set of classes, and
-  %Attr.ForbiddenClasses, which is the logical inverse.
-! You can now maintain your own configuration schema directories by
-  creating a config-schema.php file or passing an extra argument. Check
-  docs/dev-config-schema.html for more details.
-! Added HTMLPurifier_Config->serialize() method, which lets you save away
-  your configuration in a compact serial file, which you can unserialize
-  and use directly without having to go through the overhead of setup.
-- Fix bug where URIDefinition would not get cleared if it's directives got
-  changed.
-- Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0)
-- Fix bug in Linkify autoformatter involving <a><span>http://foo</span></a>
-- Make %URI.Munge not apply to links that have the same host as your host.
-- Prevent stray </body> tag from truncating output, if a second </body>
-  is present.
-. Created script maintenance/rename-config.php for renaming a configuration
-  directive while maintaining its alias.  This script does not change source code.
-. Implement namespace locking for definition construction, to prevent
-  bugs where a directive is used for definition construction but is not
-  used to construct the cache hash.
-
-3.3.0, released 2009-02-16
-! Implement CSS property 'overflow' when %CSS.AllowTricky is true.
-! Implement generic property list classess
-- Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation
-  does not do the "right thing" with characters not supported in the output
-  set.
-- Spellcheck UTF-8: The Secret To Character Encoding
-- Fix improper removal of the contents of elements with only whitespace. Thanks
-  Eric Wald for reporting.
-- Fix broken test suite in versions of PHP without spl_autoload_register()
-- Fix degenerate case with YouTube filter involving double hyphens.
-  Thanks Pierre Attar for reporting.
-- Fix YouTube rendering problem on certain versions of Firefox.
-- Fix CSSDefinition Printer problems with decorators
-- Add text parameter to unit tests, forces text output
-. Add verbose mode to command line test runner, use (--verbose)
-. Turn on unit tests for UnitConverter
-. Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0)
-. Fix newline errors that caused spurious failures when CRLF HTML Purifier was
-  tested on Linux.
-. Removed trailing whitespace from all text files, see
-  remote-trailing-whitespace.php maintenance script.
-. Convert configuration to use property list backend.
-
-3.2.0, released 2008-10-31
-# Using %Core.CollectErrors forces line number/column tracking on, whereas
-  previously you could theoretically turn it off.
-# HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please
-  use handleEnd() instead.
-! %Output.AttrSort for when you need your attributes in alphabetical order to
-  deal with a bug in FCKEditor. Requested by frank farmer.
-! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith.
-! Proper support for name attribute. It is now allowed and equivalent to the id
-  attribute in a and img tags, and is only converted to id when %HTML.TidyLevel
-  is heavy (for all doctypes).
-! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't
-  use on hand-written HTML.
-! Add error-cases for unsupported elements in MakeWellFormed. This enables
-  the strategy to be used, standalone, on untrusted input.
-! %Core.AggressivelyFixLt is on by default. This causes more sensible
-  processing of left angled brackets in smileys and other whatnot.
-! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier',
-  'phpt', 'vtest', etc. in order to only execute those tests. This supercedes
-  the --only-phpt parameter, although for backwards-compatibility the flag
-  will still work.
-! AutoParagraph auto-formatter will now preserve double-newlines upon output.
-  Users who are not performing inbound filtering, this may seem a little
-  useless, but as a bonus, the test suite and handling of edge cases is also
-  improved.
-! Experimental implementation of forms for %HTML.Trusted
-! Track column numbers when maintain line numbers is on
-! Proprietary 'background' attribute on table-related elements converted into
-  corresponding CSS.  Thanks Fusemail for sponsoring this feature!
-! Add forward(), forwardUntilEndToken(), backward() and current() to Injector
-  supertype.
-! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The
-  time of operation varies slightly from notifyEnd() as *all* end tokens are
-  processed by the injector before they are subject to the well-formedness rules.
-! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to
-  basename of image when not present.
-! %AutoFormat.DisplayLinkURI neuters <a> tags into plain text URLs.
-- Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs,
-  the other involving an undefined $is_folder error.
-- Throw error when %Core.Encoding is set to a spurious value. Previously,
-  this errored silently and returned false.
-- Redirected stderr to stdout for flush error output.
-- %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not
-  available.
-- Do not re-munge URL if the output URL has the same host as the input URL.
-  Requested by Chris.
-- Fix error in documentation regarding %Filter.ExtractStyleBlocks
-- Prevent <![CDATA[<body></body>]]> from triggering %Core.ConvertDocumentToFragment
-- Fix bug with inline elements in blockquotes conflicting with strict doctype
-- Detect if HTML support is disabled for DOM by checking for loadHTML() method.
-- Fix bug where dots and double-dots in absolute URLs without hostname were
-  not collapsed by URIFilter_MakeAbsolute.
-- Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements
-  by reordering their addition.
-- Will now throw exception on many error conditions during lexer creation; also
-  throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers
-  is being used.
-- Detect if domxml extension is loaded, and use DirectLEx accordingly.
-- Improve handling of big numbers with floating point arithmetic in UnitConverter.
-  Reported by David Morton.
-. Strategy_MakeWellFormed now operates in-place, saving memory and allowing
-  for more interesting filter-backtracking
-. New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind
-  index to reprocess tokens.
-. StringHashParser now allows for multiline sections with "empty" content;
-  previously the section would remain undefined.
-. Added --quick option to multitest.php, which tests only the most recent
-  release for each series.
-. Added --distro option to multitest.php, which accepts either 'normal' or
-  'standalone'. This supercedes --exclude-normal and --exclude-standalone
-
-3.1.1, released 2008-06-19
-# %URI.Munge now, by default, does not munge resources (for example, <img src="">)
-  In order to enable this again, please set %URI.MungeResources to true.
-! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength,
-  and height/width HTML with %HTML.MaxImgLength.
-! %URI.MungeSecretKey for secure URI munging. Thanks Chris
-  for sponsoring this feature. Check out the corresponding documentation
-  for details. (Att Nightly testers: The API for this feature changed before
-  the general release. Namely, rename your directives %URI.SecureMungeSecretKey =>
-  %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge)
-! Implemented post URI filtering. Set member variable $post to true to set
-  a URIFilter as such.
-! Allow modules to define injectors via $info_injector. Injectors are
-  automatically disabled if injector's needed elements are not found.
-! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed.
-  Thanks Chris for sponsoring. If you've been using ad hoc code from the
-  forums, PLEASE use this instead.
-! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order,
-  embedded, tag name, attribute name, CSS property name). See %URI.Munge
-  for more details. Requested by Jochem Blok.
-- Disable percent height/width attributes for img.
-- AttrValidator operations are now atomic; updates to attributes are not
-  manifest in token until end of operations. This prevents naughty internal
-  code from directly modifying CurrentToken when they're not supposed to.
-  This semantics change was requested by frank farmer.
-- Percent encoding checks enabled for URI query and fragment
-- Fix stray backslashes in font-family; CSS Unicode character escapes are
-  now properly resolved (although *only* in font-family). Thanks Takeshi Terada
-  for reporting.
-- Improve parseCDATA algorithm to take into account newline normalization
-- Account for browser confusion between Yen character and backslash in
-  Shift_JIS encoding. This fix generalizes to any other encoding which is not
-  a strict superset of printable ASCII. Thanks Takeshi Terada for reporting.
-- Fix missing configuration parameter in Generator calls. Thanks vs for the
-  partial patch.
-- Improved adherence to Unicode by checking for non-character codepoints.
-  Thanks Geoffrey Sneddon for reporting. This may result in degraded
-  performance for extremely large inputs.
-- Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok
-  for reporting.
-. Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient
-  handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses
-  this class.
-. API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative)
-  to __construct($min, $max). __construct(true) is equivalent to
-  __construct('0').
-. Added HTMLPurifier_AttrDef_Switch class
-. Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method
-  up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules
-  get this called with the configuration object.  All modules now
-  use this rather than __construct(), although legacy code using constructors
-  will still work--the new format, however, lets modules access the
-  configuration object for HTML namespace dependant tweaks.
-. AttrDef_HTML_Pixels now takes a single construction parameter, pixels.
-. ConfigSchema data-structure heavily optimized; on average it uses a third
-  the memory it did previously. The interface has changed accordingly,
-  consult changes to HTMLPurifier_Config for details.
-. Variable parsing types now are magic integers instead of strings
-. Added benchmark for ConfigSchema
-. HTMLPurifier_Generator requires $config and $context parameters. If you
-  don't know what they should be, use HTMLPurifier_Config::createDefault()
-  and new HTMLPurifier_Context().
-. Printers now properly distinguish between output configuration, and
-  target configuration. This is not applicable to scripts using
-  the Printers for HTML Purifier related tasks.
-. HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise
-  fatal errors will ensue.
-. URIFilter->prepare can return false in order to abort loading of the filter
-. Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds
-  an external resource.
-. %URI.Munge functionality factored out into a post-filter class.
-. Added CurrentCSSProperty context variable during CSS validation
-
-3.1.0, released 2008-05-18
-# Unnecessary references to objects (vestiges of PHP4) removed from method
-  signatures.  The following methods do not need references when assigning from
-  them and will result in E_STRICT errors if you try:
-    + HTMLPurifier_Config->get*Definition() [* = HTML, CSS]
-    + HTMLPurifier_ConfigSchema::instance()
-    + HTMLPurifier_DefinitionCacheFactory::instance()
-    + HTMLPurifier_DefinitionCacheFactory->create()
-    + HTMLPurifier_DoctypeRegistry->register()
-    + HTMLPurifier_DoctypeRegistry->get()
-    + HTMLPurifier_HTMLModule->addElement()
-    + HTMLPurifier_HTMLModule->addBlankElement()
-    + HTMLPurifier_LanguageFactory::instance()
-# Printer_ConfigForm's get*() functions were static-ified
-# %HTML.ForbiddenAttributes requires attribute declarations to be in the
-  form of tag@attr, NOT tag.attr (which will throw an error and won't do
-  anything). This is for forwards compatibility with XML; you'd do best
-  to migrate an %HTML.AllowedAttributes directives to this syntax too.
-! Allow index to be false for config from form creation
-! Added HTMLPurifier::VERSION constant
-! Commas, not dashes, used for serializer IDs. This change is forwards-compatible
-  and allows for version numbers like "3.1.0-dev".
-! %HTML.Allowed deals gracefully with whitespace anywhere, anytime!
-! HTML Purifier's URI handling is a lot more robust, with much stricter
-  validation checks and better percent encoding handling. Thanks Gareth Heyes
-  for indicating security vulnerabilities from lax percent encoding.
-! Bootstrap autoloader deals more robustly with classes that don't exist,
-  preventing class_exists($class, true) from barfing.
-- InterchangeBuilder now alphabetizes its lists
-- Validation error in configdoc output fixed
-- Iconv and other encoding errors muted even with custom error handlers that

-  of DOM), HTML Purifier punts to DirectLex
-- Fatal error with unserialization of ScriptRequired
-- Created directories are now chmod'ed properly
-- Fixed bug with fallback languages in LanguageFactory
-- Standalone testing setup properly with autoload
-. Out-of-date documentation revised
-. UTF-8 encoding check optimization as suggested by Diego
-. HTMLPurifier_Error removed in favor of exceptions
-. More copy() function removed; should use clone instead
-. More extensive unit tests for HTMLDefinition
-. assertPurification moved to central harness
-. HTMLPurifier_Generator accepts $config and $context parameters during
-  instantiation, not runtime
-. Double-quotes outside of attribute values are now unescaped
-
-3.1.0rc1, released 2008-04-22
-# Autoload support added. Internal require_once's removed in favor of an
-  explicit require list or autoloading. To use HTML Purifier,
-  you must now either use HTMLPurifier.auto.php
-  or HTMLPurifier.includes.php; setting the include path and including
-  HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php
-  as well to register our autoload handler (or modify your autoload function
-  to check HTMLPurifier_Bootstrap::getPath($class)). You can also use
-  HTMLPurifier.safe-includes.php for a less performance friendly but more
-  user-friendly library load.
-# HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema
-  information is stored in the ConfigSchema directory, and the
-  maintenance/generate-schema-cache.php generates the schema.ser file, which
-  is now instantiated. Support for userland schema changes coming soon!
-# HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive
-  alias; to get rid of these errors just modify your configuration to use
-  the new directive name.
-# HTMLPurifier->addFilter is deprecated; built-in filters can now be
-  enabled using %Filter.$filter_name or by setting your own filters using
-  %Filter.Custom
-# Directive-level safety properties superceded in favor of module-level
-  safety. Internal method HTMLModule->addElement() has changed, although
-  the externally visible HTMLDefinition->addElement has *not* changed.
-! Extra utility classes for testing and non-library operations can
-  be found in extras/. Specifically, these are FSTools and ConfigDoc.
-  You may find a use for these in your own project, but right now they
-  are highly experimental and volatile.
-! Integration with PHPT allows for automated smoketests
-! Limited support for proprietary HTML elements, namely <marquee>, sponsored
-  by Chris. You can enable them with %HTML.Proprietary if your client
-  demands them.
-! Support for !important CSS cascade modifier. By default, this will be stripped
-  from CSS, but you can enable it using %CSS.AllowImportant
-! Support for display and visibility CSS properties added, set %CSS.AllowTricky
-  to true to use them.
-! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception.
-  Developer error (not enduser error) can cause these to be triggered.
-! Experimental kses() wrapper introduced with HTMLPurifier.kses.php
-! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without
-  mucking around with HTMLPurifier_CSSDefinition
-! ConfigDoc output has been enhanced with version and deprecation info.
-! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented.
-- Autoclose now operates iteratively, i.e. <span><span><div> now has
-  both span tags closed.
-- Various HTMLPurifier_Config convenience functions now accept another parameter
-  $schema which defines what HTMLPurifier_ConfigSchema to use besides the
-  global default.

-  static methods.
-. A couple of new historical maintenance scripts were added.
-. HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files
-. tests/index.php can now be run from any directory.
-. HTMLPurifier_Token subclasses split into seperate files
-. HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php
-. HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier
-. New --php=php flag added, allows PHP executable to be specified (command
-  line only!)
-. htmlpurifier_add_test() preferred method to translate test files in to
-  classes, because it handles PHPT files too.
-. Debugger class is deprecated and will be removed soon.
-. Command line argument parsing for testing scripts revamped, now --opt value
-  format is supported.
-. Smoketests now cleanup after magic quotes
-. Generator now can output comments (however, comments are still stripped
-  from HTML Purifier output)
-. HTMLPurifier_ConfigSchema->validate() deprecated in favor of

-. Command line scripts now honor exit codes
-. When --flush fails in unit testers, abort tests and print message
-. Improved documentation in docs/dev-flush.html about the maintenance scripts
-. copy() methods removed in favor of clone keyword

-  <http://csstidy.sourceforge.net/>. You can access the blocks with the
-  'StyleBlocks' Context variable ($purifier->context->get('StyleBlocks')).
-  The output CSS can also be "scoped" for a specific element, use:
-  %Filter.ExtractStyleBlocksScope
-! Experimental support for some proprietary CSS attributes allowed:

-
-2.1.2, released 2007-09-03
-! Implemented Object module for trusted users
-! Implemented experimental HTML5 parsing mode using PH5P. To use, add
-  this to your code:
-        require_once 'HTMLPurifier/Lexer/PH5P.php';
-        $config->set('Core', 'LexerImpl', 'PH5P');
-  Note that this Lexer introduces some classes not in the HTMLPurifier
-  namespace.  Also, this is PHP5 only.
-! CSS property border-spacing implemented
-- Fix non-visible parsing error in DirectLex with empty tags that have
-  slashes inside attribute values.
-- Fix typo in CSS definition: border-collapse:seperate; was incorrectly
-  accepted as valid CSS. Usually non-visible, because this styling is the
-  default for tables in most browsers. Thanks Brett Zamir for pointing
-  this out.
-- Fix validation errors in configuration form
-- Hammer out a bunch of edge-case bugs in the standalone distribution
-- Inclusion reflection removed from URISchemeRegistry; you must manually
-  include any new schema files you wish to use

-. Single test methods can be invoked by prefixing with __only
-
-2.1.0, released 2007-08-02
-# flush-htmldefinition-cache.php superseded in favor of a generic
-  flush-definition-cache.php script, you can clear a specific cache
-  by passing its name as a parameter to the script
-! Phorum mod implemented for HTML Purifier
-! With %Core.AggressivelyFixLt, <3 and similar emoticons no longer
-  trigger HTML removal in PHP5 (DOMLex). This directive is not necessary
-  for PHP4 (DirectLex).
-! Standalone file now available, which greatly reduces the amount of
-  includes (although there are still a few files that reside in the
-  standalone folder)
-! Relative URIs can now be transformed into their absolute equivalents
-  using %URI.Base and %URI.MakeAbsolute
-! Ruby implemented for XHTML 1.1

-  for output cache invalidation
-. ConfigForm printer now can retrieve CSS and JS files as strings, in
-  case HTML Purifier's directory is not publically accessible
-. Introduce new text/itext configuration directive values: these represent
-  longer strings that would be more appropriately edited with a textarea
-. Allow newlines to act as separators for lists, hashes, lookups and
-  %HTML.Allowed
-. ConfigForm generates textareas instead of text inputs for lists, hashes,
-  lookups, text and itext fields
-. Hidden element content removal genericized: %Core.HiddenElements can
-  be used to customize this behavior, by default <script> and <style> are
-  hidden
-. Added HTMLPURIFIER_PREFIX constant, should be used instead of dirname(__FILE__)
-. Custom ChildDef added to default include list
-. URIScheme reflection improved: will not attempt to include file if class
-  already exists. May clobber autoload, so I need to keep an eye on it
-. ConfigSchema heavily optimized, will only collect information and validate
-  definitions when HTMLPURIFIER_SCHEMA_STRICT is true.
-. AttrDef_URI unit tests and implementation refactored
-. benchmarks/ directory now protected from public view with .htaccess file;
-  run the tests via command line
-. URI scheme is munged off if there is no authority and the scheme is the
-  default one

-  maximum extensibility
-
-2.0.1, released 2007-06-27
-! Tag auto-closing now based on a ChildDef heuristic rather than a
-  manually set auto_close array; some behavior may change
-! Experimental AutoFormat functionality added: auto-paragraph and
-  linkify your HTML input by setting %AutoFormat.AutoParagraph and
-  %AutoFormat.Linkify to true
-! Newlines normalized internally, and then converted back to the
-  value of PHP_EOL. If this is not desired, set your newline format
-  using %Output.Newline.
-! Beta error collection, messages are implemented for the most generic
-  cases involving Lexing or Strategies
-- Clean up special case code for <script> tags
-- Reorder includes for DefinitionCache decorators, fixes a possible
-  missing class error
-- Fixed bug where manually modified definitions were not saved via cache
-  (mostly harmless, except for the fact that it would be a little slower)

-  others when revision numbers are unequal
-- Improve Serializer DefinitionCache directory permissions checks
-- DefinitionCache no longer throws errors when it encounters old
-  serial files that do not conform to the current style

-  much easier selective embedding of configuration values
-. Doctype objects now accept public and system DTD identifiers
-. %HTML.Doctype is now constrained by specific values, to specify a custom
-  doctype use new %HTML.CustomDoctype

SLOW

+
+SLOW
+  also known as the HELP ME LIBRARY IS TOO SLOW MY PAGE TAKE TOO LONG LOAD page
+
+HTML Purifier is a very powerful library.  But with power comes great
+responsibility, or, at least, longer execution times.  Remember, this
+library isn't lightly grazing over submitted HTML: it's deconstructing
+the whole thing, rigorously checking the parts, and then putting it
+back together.
+
+So, if it so turns out that HTML Purifier is kinda too slow for outbound
+filtering, you've got a few options:
+
+1. Inbound filtering - perform filtering of HTML when it's submitted by the
+user.  Since the user is already submitting something, an extra half a
+second tacked on to the load time probably isn't going to be that huge of
+a problem.  Then, displaying the content is a simple a manner of outputting
+it directly from your database/filesystem.  The trouble with this method is
+that your user loses the original text, and when doing edits, will be
+handling the filtered text.  While this may be a good thing, especially if
+you're using a WYSIWYG editor, it can also result in data-loss if a user
+makes a typo.
+
+2. Caching the filtered output - accept the submitted text and put it
+unaltered into the database, but then also generate a filtered version and
+stash that in the database.  Serve the filtered version to readers, and the
+unaltered version to editors.  If need be, you can invalidate the cache and
+have the cached filtered version be regenerated on the first page view.  Pros?
+Full data retention.  Cons?  It's more complicated, and opens other editors
+up to XSS if they are using a WYSIWYG editor (to fix that, they'd have to
+be able to get their hands on the *really* original text served in plaintext
+mode).
+
+In short, inbound filtering is almost as simple as outbound filtering, but
+it has some drawbacks which cannot be fixed unless you save both the original
+and the filtered versions.
+
+There is a third option: profile and optimize HTMLPurifier yourself.  Be sure
+to report back your results if you decide to do that!  Especially if you
+port HTML Purifier to C++.  ;-)

- - Inputs don't do the right thing with submit
- - Fix "<.<" bug (trailing < is removed if not EOD)
- - Build in better internal state dumps and debugging tools for remote

- - Allowed/Allowed* have strange interactions when both set
- - Transform lone embeds into object tags
-
-FUTURE VERSIONS
----------------
-
-4.2 release [OMG CONFIG PONIES]
- ! Fix Printer. It's from the old days when we didn't have decent XML classes
- ! Factor demo.php into a set of Printer classes, and then create a stub
-   file for users here (inside the actual HTML Purifier library)
- - Fix error handling with form construction
- - Do encoding validation in Printers, or at least, where user data comes in
- - Config: Add examples to everything (make built-in which also automatically
-   gives output)
- - Add "register" field to config schemas to eliminate dependence on
-   naming conventions (try to remember why we ultimately decided on tihs)
-
-5.0 release [HTML 5]
- # Swap out code to use html5lib tokenizer and tree-builder
- ! Allow turning off of FixNesting and required attribute insertion
-
-5.1 release [It's All About Trust] (floating)
- # Implement untrusted, dangerous elements/attributes
- # Implement IDREF support (harder than it seems, since you cannot have
-   IDREFs to non-existent IDs)
-     - Implement <area> (client and server side image maps are blocking
-       on IDREF support)
- # Frameset XHTML 1.0 and HTML 4.01 doctypes
- - Figure out how to simultaneously set %CSS.Trusted and %HTML.Trusted (?)
-
-5.2 release [Error'ed]
+1.5 release
  # Error logging for filtering/cleanup procedures
+    - Requires I18N facilities to be created first (COMPLEX)
+
+1.6 release
+ # Add pre-packaged "levels" of cleaning (custom behavior already done)
+ - More fine-grained control over escaping behavior
+    - Silently drop content inbetween SCRIPT tags (can be generalized to allow
+      specification of elements that, when detected as foreign, trigger removal
+      of children, although unbalanced tags could wreck havoc (or at least
+      delete the rest of the document)).
+
+1.7 release
  # Additional support for poorly written HTML
+    - Implement all non-essential attribute transforms (BIG!)
     - Microsoft Word HTML cleaning (i.e. MsoNormal, but research essential!)
     - Friendly strict handling of <address> (block -> <br>)
- - XSS-attempt detection--certain errors are flagged XSS-like
- - Append something to duplicate IDs so they're still usable (impl. note: the
-   dupe detector would also need to detect the suffix as well)
 
-6.0 release [Beyond HTML]
- # Legit token based CSS parsing (will require revamping almost every
-   AttrDef class). Probably will use CSSTidy
- # More control over allowed CSS properties using a modularization
- # IRI support (this includes IDN)
- - Standardize token armor for all areas of processing
+2.0 release
+ # Formatters for plaintext (COMPLEX)
+    - Auto-paragraphing (be sure to leverage fact that we know when things
+      shouldn't be paragraphed, such as lists and tables).
+    - Linkify URLs
+    - Smileys
+    - Linkification for HTML Purifier docs: notably configuration and classes
 
-7.0 release [To XML and Beyond]
+3.0 release
  - Extended HTML capabilities based on namespacing and tag transforms (COMPLEX)
     - Hooks for adding custom processors to custom namespaced tags and
       attributes, offer default implementation
     - Lots of documentation and samples
+ - XHTML 1.1 support
 
 Ongoing
- - More refactoring to take advantage of PHP5's facilities
- - Refactor unit tests into lots of test methods

-    - Also, a FAQ for extension writers with HTML Purifier
+    - Drupal
+    - WordPress
+    - eFiction
+    - more! (look for ones that use WYSIWYGs)
 
-AutoFormat
- - Smileys
- - Syntax highlighting (with GeSHi) with <pre> and possibly <?php
- - Look at http://drupal.org/project/Modules/category/63 for ideas
-
-Neat feature related
- ! Support exporting configuration, so users can easily tweak settings
-   in the demo, and then copy-paste into their own setup
- - Advanced URI filtering schemes (see docs/proposal-new-directives.txt)
- - Allow scoped="scoped" attribute in <style> tags; may be troublesome
-   because regular CSS has no way of uniquely identifying nodes, so we'd
-   have to generate IDs
- - Explain how to use HTML Purifier in non-PHP languages / create
-   a simple command line stub (or complicated?)
+Unknown release (on a scratch-an-itch basis)
  - Fixes for Firefox's inability to handle COL alignment props (Bug 915)
  - Automatically add non-breaking spaces to empty table cells when
    empty-cells:show is applied to have compatibility with Internet Explorer
- - Table of Contents generation (XHTML Compiler might be reusable). May also
-   be out-of-band information.
- - Full set of color keywords. Also, a way to add onto them without
-   finalizing the configuration object.
- - Write a var_export and memcached DefinitionCache - Denis
- - Built-in support for target="_blank" on all external links
  - Convert RTL/LTR override characters to <bdo> tags, or vice versa on demand.
    Also, enable disabling of directionality
- ? Externalize inline CSS to promote clean HTML, proposed by Sander Tekelenburg
- ? Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
+ - Append something to duplicate IDs so they're still usable (impl. note: the
+   dupe detector would also need to detect the suffix as well)
+ - Have 'lang' attribute be checked against official lists
+ - Docs on how to embed YouTube videos (and friends) without patches
+
+Encoding workarounds
+ - Non-lossy dumb alternate character encoding transformations, achieved by
+   numerically encoding all non-ASCII characters
+ - Semi-lossy dumb alternate character encoding transformations, achieved by
+   encoding all characters that have string entity equivalents
+
+Requested
+ - Native content compression, whitespace stripping (don't rely on Tidy, make
+   sure we don't remove from <pre> or related tags)
+ - Win32 Phalanger C# binaries (?)
+ - Remove redundant tags, ex. <u><u>Underlined</u></u>. Implementation notes:
     1. Analyzing which tags to remove duplicants
     2. Ensure attributes are merged into the parent tag
     3. Extend the tag exclusion system to specify whether or not the
     contents should be dropped or not (currently, there's code that could do
     something like this if it didn't drop the inner text too.)
 
-Maintenance related (slightly boring)
- # CHMOD install script for PEAR installs
- ! Factor out command line parser into its own class, and unit test it
- - Reduce size of internal data-structures (esp. HTMLDefinition)
- - Allow merging configurations.  Thus,
-        a -> b -> default
-        c -> d -> default
-   becomes
-        a -> b -> c -> d -> default
-   Maybe allow more fine-grained tuning of this behavior. Alternatively,
-   encourage people to use short plist depths before building them up.
- - Time PHPT tests
-
-ChildDef related (very boring)
- - Abstract ChildDef_BlockQuote to work with all elements that only
-   allow blocks in them, required or optional
- - Implement lenient <ruby> child validation
-
 Wontfix
  - Non-lossy smart alternate character encoding transformations (unless
    patch provided)
- - Pretty-printing HTML: users can use Tidy on the output on entire page
- - Native content compression, whitespace stripping: use gzip if this is
-   really important

+<p><i>Taiji</i> is an ancient Chinese tradition of movement systems that is associated with philosophy, physiology, psychology, geometry and dynamics. It is the slowest form of martial arts and is meant to improve the internal spirit.   It is soothing to the soul and extremely invigorating. </p> 
 
 <p>The founder of Taiji was Zhang Sanfeng (Chang San-feng), who was a monk of the Wu Dang (Wu Tang) Monastery and lived in the period from 1391 to 1459. His exercises stressed suppleness and elasticity as opposed to the hardness and force of other martial art styles. Several centuries old, Taiji was originally developed as a form of self-defense, emphasizing strength, balance, flexibility and speed. Tai Chi also differs from other martial arts in that it is based on the Taoist religion and aims to avoid aggressive forces. </p>

-Configuration Backwards-Compatibility Breaks
-
-In version 4.0.0, the configuration subsystem (composed of the outwards
-facing Config class, as well as the ConfigSchema and ConfigSchema_Interchange
-subsystems), was significantly revamped to make use of property lists.
-While most of the changes are internal, some internal APIs were changed for the
-sake of clarity. HTMLPurifier_Config was kept completely backwards compatible,
-although some of the functions were retrofitted with an unambiguous alternate
-syntax. Both of these changes are discussed in this document.
-
-
-
-1. Outwards Facing Changes
---------------------------------------------------------------------------------
-
-The HTMLPurifier_Config class now takes an alternate syntax. The general rule
-is:
-
-    If you passed $namespace, $directive, pass "$namespace.$directive"
-    instead.
-
-An example:
-
-    $config->set('HTML', 'Allowed', 'p');
-
-becomes:
-
-    $config->set('HTML.Allowed', 'p');
-
-New configuration options may have more than one namespace, they might
-look something like %Filter.YouTube.Blacklist. While you could technically
-set it with ('HTML', 'YouTube.Blacklist'), the logical extension
-('HTML', 'YouTube', 'Blacklist') does not work.
-
-The old API will still work, but will emit E_USER_NOTICEs.
-
-
-
-2. Internal API Changes
---------------------------------------------------------------------------------
-
-Some overarching notes: we've completely eliminated the notion of namespace;
-it's now an informal construct for organizing related configuration directives.
-
-Also, the validation routines for keys (formerly "$namespace.$directive")
-have been completely relaxed. I don't think it really should be necessary.
-
-2.1 HTMLPurifier_ConfigSchema
-
-First off, if you're interfacing with this class, you really shouldn't.
-HTMLPurifier_ConfigSchema_Builder_ConfigSchema is really the only class that
-should ever be creating HTMLPurifier_ConfigSchema, and HTMLPurifier_Config the
-only class that should be reading it.
-
-All namespace related methods were removed; they are completely unnecessary
-now. Any $namespace, $name arguments must be replaced with $key (where
-$key == "$namespace.$name"), including for addAlias().
-
-The $info and $defaults member variables are no longer indexed as
-[$namespace][$name]; they are now indexed as ["$namespace.$name"].
-
-All deprecated methods were finally removed, after having yelled at you as
-an E_USER_NOTICE for a while now.
-
-2.2 HTMLPurifier_ConfigSchema_Interchange
-
-Member variable $namespaces was removed.
-
-2.3 HTMLPurifier_ConfigSchema_Interchange_Id
-
-Member variable $namespace and $directive removed; member variable $key added.
-Any method that took $namespace, $directive now takes $key.
-
-2.4 HTMLPurifier_ConfigSchema_Interchange_Namespace
-
-Removed.

-Configuration naming
-
-HTML Purifier 4.0.0 features a new configuration naming system that
-allows arbitrary nesting of namespaces.  While there are certain cases
-in which using two namespaces is obviously better (the canonical example
-is where we were using AutoFormatParam to contain directives for AutoFormat
-parameters), it is unclear whether or not a general migration to highly
-namespaced directives is a good idea or not.
-
-== Case studies ==
-
-=== Attr.* ===
-
-We have a dead duck HTML.Attr.Name.UseCDATA which migrated before we decided
-to think this out thoroughly.
-
-We currently have a large number of directives in the Attr.* namespace.
-These directives tweak the behavior of some HTML attributes.  They have
-the properties:
-
-* While they apply to only one attribute at a time, the attribute can
-  span over multiple elements (not necessarily all attributes, either).
-  The information of which elements it impacts is either omitted or
-  informally stated (EnableID applies to all elements, DefaultImageAlt
-  applies to <img> tags, AllowedRev doesn't say but only applies to a tags).
-
-* There is a certain degree of clustering that could be applied, especially
-  to the ID directives.  The clustering could be done with respect to
-  what element/attribute was used, i.e.
-
-    *.id -> EnableID, IDBlacklistRegexp, IDBlacklist, IDPrefixLocal, IDPrefix
-    img.src -> DefaultInvalidImage
-    img.alt -> DefaultImageAlt, DefaultInvalidImageAlt
-    bdo.dir -> DefaultTextDir
-    a.rel -> AllowedRel
-    a.rev -> AllowedRev
-    a.target -> AllowedFrameTargets
-    a.name -> Name.UseCDATA
-
-* The directives often reference generic attribute types that were specified
-  in the DTD/specification.  However, some of the behavior specifically relies
-  on the fact that other use cases of the attribute are not, at current,
-  supported by HTML Purifier.
-
-    AllowedRel, AllowedRev -> heavily <a> specific; if <link> ends up being
-        allowed, we will also have to give users specificity there (we also
-        want to preserve generality) DTD %Linktypes, HTML5 distinguishes
-        between <link> and <a>/<area>
-    AllowedFrameTargets -> heavily <a> specific, but also used by <area>
-        and <form>. Transitional DTD %FrameTarget, not present in strict,
-        HTML5 calls them "browsing contexts"
-    Default*Image* -> as a default parameter, is almost entirely exlcusive
-        to <img>
-    EnableID -> global attribute
-    Name.UseCDATA -> heavily <a> specific, but has heavy other usage by
-        many things
-
-== AutoFormat.* ==
-
-These have the fairly normal pluggable architecture that lends itself to
-large amounts of namespaces (pluggability may be the key to figuring
-out when gratuitous namespacing is good.)  Properties:
-
-* Boolean directives are fair game for being namespaced: for example,
-  RemoveEmpty.RemoveNbsp triggers RemoveEmpty.RemoveNbsp.Exceptions,
-  the latter of which only makes sense when RemoveEmpty.RemoveNbsp
-  is set to true. (The same applies to RemoveNbsp too)
-
-The AutoFormat string is a bit long, but is the only bit of repeated
-context.
-
-== Core.* ==
-
-Core is the potpourri of directives, mostly regarding some minor behavioral
-tweaks for HTML handling abilities.
-
-    AggressivelyFixLt
-    ConvertDocumentToFragment
-    DirectLexLineNumberSyncInterval
-    LexerImpl
-    MaintainLineNumbers
-        Lexer
-    CollectErrors
-    Language
-        Error handling (Language is ostensibly a little more general, but
-        it's only used for error handling right now)

-
-    <p>
-      HTML Purifier has a fairly complex system for configuration. Users
-      interact with a <code>HTMLPurifier_Config</code> object to
-      set configuration directives. The values they set are validated according
-      to a configuration schema, <code>HTMLPurifier_ConfigSchema</code>.
-    </p>
-
-    <p>
-      The schema is mostly transparent to end-users, but if you're doing development
-      work for HTML Purifier and need to define a new configuration directive,
-      you'll need to interact with it. We'll also talk about how to define
-      userspace configuration directives at the very end.
-    </p>
-
-    <h2>Write a directive file</h2>
-
-    <p>
-      Directive files define configuration directives to be used by
-      HTML Purifier. They are placed in <code>library/HTMLPurifier/ConfigSchema/schema/</code>
-      in the form <code><em>Namespace</em>.<em>Directive</em>.txt</code> (I
-      couldn't think of a more descriptive file extension.)
-      Directive files are actually what we call <code>StringHash</code>es,
-      i.e. associative arrays represented in a string form reminiscent of
-      <a href="http://qa.php.net/write-test.php">PHPT</a> tests. Here's a
-      sample directive file, <code>Test.Sample.txt</code>:
-    </p>
-
-    <pre>Test.Sample
-TYPE: string/null
-DEFAULT: NULL
-ALLOWED: 'foo', 'bar'
-VALUE-ALIASES: 'baz' => 'bar'
-VERSION: 3.1.0
---DESCRIPTION--
-This is a sample configuration directive for the purposes of the
-&lt;code&gt;dev-config-schema.html&lt;code&gt; documentation.
---ALIASES--
-Test.Example</pre>

-

-        Each of these keys can be expressed in the short format
-        (<code>KEY: Value</code>) or the long format
-        (<code>--KEY--</code> with value beneath). You must use the
-        long format if multiple lines are needed, or if a long format
-        has been used already (that's why <code>ALIASES</code> in our
-        example is in the long format); otherwise, it's user preference.
-      </li>
-      <li>
-        The HTML descriptions should be wrapped at about 80 columns; do
-        not rely on editor word-wrapping.

-      The examples represent what will be returned out of the configuration
-      object; users have a little bit of leeway when setting configuration
-      values (for example, a lookup value can be specified as a list;
-      HTML Purifier will flip it as necessary.) These types are defined
-      in <a href="http://repo.or.cz/w/htmlpurifier.git?a=blob;hb=HEAD;f=library/HTMLPurifier/VarParser.php">
-      library/HTMLPurifier/VarParser.php</a>.

-      library/HTMLPurifier/ConfigSchema/InterchangeBuilder.php</a>, as well
-      as <a href="http://repo.or.cz/w/htmlpurifier.git?a=blob;hb=HEAD;f=library/HTMLPurifier/ConfigSchema/Interchange/Directive.php">
-      library/HTMLPurifier/ConfigSchema/Interchange/Directive.php</a> for
-      the semantics of the parsed values.
-    </p>
-
-    <h2>Refreshing the cache</h2>
-
-    <p>
-      You may have noticed that your directive file isn't doing anything
-      yet. That's because it hasn't been added to the runtime
-      <code>HTMLPurifier_ConfigSchema</code> instance. Run
-      <code>maintenance/generate-schema-cache.php</code> to fix this.
-      If there were no errors, you're good to go! Don't forget to add
-      some unit tests for your functionality!
-    </p>
-
-    <p>
-      If you ever make changes to your configuration directives, you
-      will need to run this script again.
-    </p>
-    <h2>Adding in-house schema definitions</h2>
-
-    <p>
-      Placing stuff directly in HTML Purifier's source tree is generally not a
-      good idea, so HTML Purifier 4.0.0+ has some facilities in place to make your
-      life easier.
-    </p>
-
-    <p>
-      The first is to pass an extra parameter to <code>maintenance/generate-schema-cache.php</code>
-      with the location of your directory (relative or absolute path will do). For example,
-      if I'm storing my custom definitions in <em>/var/htmlpurifier/myschema</em>, run:
-      <code>php maintenance/generate-schema-cache.php /var/htmlpurifier/myschema</code>.
-    </p>
-
-    <p>
-      Alternatively, you can create a small loader PHP file in the HTML Purifier base
-      directory named <code>config-schema.php</code> (this is the same directory
-      you would place a <code>test-settings.php</code> file).  In this file, add
-      the following line for each directory you want to load:
-    </p>
-
-<pre>$builder-&gt;buildDir($interchange, '/var/htmlpurifier/myschema');</pre>
-
-    <p>You can even load a single file using:</p>
-
-<pre>$builder-&gt;buildFile($interchange, '/var/htmlpurifier/myschema/MyApp.Directive.txt');</pre>
-
-    <p>Storing custom definitions that you don't plan on sending back upstream in
-    a separate directory is <em>definitely</em> a good idea! Additionally, picking
-    a good namespace can go a long way to saving you grief if you want to use
-    someone else's change, but they picked the same name, or if HTML Purifier
-    decides to add support for a configuration directive that has the same name.</p>
-
-    <!-- TODO: how to name directives that rely on naming conventions -->
-
-    <h2>Errors</h2>
-
-    <p>
-      All directive files go through a rigorous validation process
-      through <a href="http://repo.or.cz/w/htmlpurifier.git?a=blob;hb=HEAD;f=library/HTMLPurifier/ConfigSchema/Validator.php">
-      library/HTMLPurifier/ConfigSchema/Validator.php</a>, as well
-      as some basic checks during building. While
-      listing every error out here is out-of-scope for this document, we
-      can give some general tips for interpreting error messages.
-      There are two types of errors: builder errors and validation errors.
-    </p>
-
-    <h3>Builder errors</h3>
-
-    <blockquote>
-      <p>
-        <strong>Exception:</strong> Expected type string, got
-        integer in DEFAULT in directive hash 'Ns.Dir'
-      </p>
-    </blockquote>
-
-    <p>
-      You can identify a builder error by the keyword "directive hash."
-      These are the easiest to deal with, because they directly correspond
-      with your directive file. Find the offending directive file (which
-      is the directive hash plus the .txt extension), find the
-      offending index ("in DEFAULT" means the DEFAULT key) and fix the error.
-      This particular error would occur if your default value is not the same
-      type as TYPE.
-    </p>
-
-    <h3>Validation errors</h3>
-
-    <blockquote>
-      <p>
-        <strong>Exception:</strong> Alias 3 in valueAliases in directive
-        'Ns.Dir' must be a string
-      </p>
-    </blockquote>
-
-    <p>
-      These are a little trickier, because we're not actually validating
-      your directive file, or even the direct string hash representation.
-      We're validating an Interchange object, and the error messages do
-      not mention any string hash keys.
-    </p>
-
-    <p>
-      Nevertheless, it's not difficult to figure out what went wrong.
-      Read the "context" statements in reverse:
-    </p>
-
-    <dl>
-      <dt>in directive 'Ns.Dir'</dt>
-        <dd>This means we need to look at the directive file <code>Ns.Dir.txt</code></dd>
-      <dt>in valueAliases</dt>
-        <dd>There's no key actually called this, but there's one that's close:
-          VALUE-ALIASES. Indeed, that's where to look.</dd>
-      <dt>Alias 3</dt>
-        <dd>The value alias that is equal to 3 is the culprit.</dd>
-    </dl>
-
-    <p>
-      In this particular case, you're not allowed to alias integers values to
-      strings values.
-    </p>
-
-    <p>
-      The most difficult part is translating the Interchange member variable (valueAliases)
-      into a directive file key (VALUE-ALIASES), but there's a one-to-one
-      correspondence currently. If the two formats diverge, any discrepancies
-      will be described in <a href="http://repo.or.cz/w/htmlpurifier.git?a=blob;hb=HEAD;f=library/HTMLPurifier/ConfigSchema/InterchangeBuilder.php">
-      library/HTMLPurifier/ConfigSchema/InterchangeBuilder.php</a>.
-    </p>
-
-    <h2>Internals</h2>
-
-    <p>
-      Much of the configuration schema framework's codebase deals with
-      shuffling data from one format to another, and doing validation on this
-      data.
-      The keystone of all of this is the <code>HTMLPurifier_ConfigSchema_Interchange</code>
-      class, which represents the purest, parsed representation of the schema.
-    </p>
-
-    <p>
-      Hand-writing this data is unwieldy, however, so we write directive files.
-      These directive files are parsed by <code>HTMLPurifier_StringHashParser</code>
-      into <code>HTMLPurifier_StringHash</code>es, which then
-      are run through <code>HTMLPurifier_ConfigSchema_InterchangeBuilder</code>
-      to construct the interchange object.
-    </p>
-
-    <p>
-      From the interchange object, the data can be siphoned into other forms
-      using <code>HTMLPurifier_ConfigSchema_Builder</code> subclasses.
-      For example, <code>HTMLPurifier_ConfigSchema_Builder_ConfigSchema</code>
-      generates a runtime <code>HTMLPurifier_ConfigSchema</code> object,
-      which <code>HTMLPurifier_Config</code> uses to validate its incoming
-      data. There is also an XML serializer, which is used to build documentation.

-<p>
-    If you've been poking around the various folders in HTML Purifier,
-    you may have noticed the <code>maintenance</code> directory.  Almost
-    all of these scripts are devoted to flushing out the various caches
-    HTML Purifier uses.  Normal users don't have to worry about this:
-    regular library usage is transparent.  However, when doing development
-    work on HTML Purifier, you may find you have to flush one of the
-    caches.
-</p>
-
-<p>
-    As a general rule of thumb, run <code>flush.php</code> whenever you make
-    any <em>major</em> changes, or when tests start mysteriously failing.
-    In more detail, run this script if:
-</p>
-
-<ul>
-    <li>
-        You added new source files to HTML Purifier's main library.
-        (see <code>generate-includes.php</code>)
-    </li>
-    <li>
-        You modified the configuration schema (see
-        <code>generate-schema-cache.php</code>). This usually means
-        adding or modifying files in <code>HTMLPurifier/ConfigSchema/schema/</code>,
-        although in rare cases modifying <code>HTMLPurifier/ConfigSchema.php</code>
-        will also require this.
-    </li>
-    <li>
-        You modified a Definition, or its subsystems. The most usual candidate
-        is <code>HTMLPurifier/HTMLDefinition.php</code>, which also encompasses
-        the files in <code>HTMLPurifier/HTMLModule/</code> as well as if you've
-        <a href="enduser-customize.html">customizing definitions</a> without
-        the cache disabled. (see <code>flush-generation-cache.php</code>)
-    </li>
-    <li>
-        You modified source files, and have been using the standalone
-        version from the full installation. (see <code>generate-standalone.php</code>)
-    </li>
-</ul>

-Some of these optional components are optionally included (Filter,
-Language, Lexer, Printer), while others are included all the time
-(Injector, URIFilter, HTMLModule, URIScheme). We will stipulate that these
-are all developer specified: it is conceivable that certain Tokens are not
-used, but this is user-dependent and should not be trusted.
-
-We should come up with a consistent way to handle these things and ensure
-that we get the maximum performance when there is bytecode caches and
-when there are not. Unfortunately, these two goals seem contrary to each
-other.
-
-A peripheral issue is the performance of ConfigSchema, which has been
-shown take a large, constant amount of initialization time, and is
-intricately linked to the issue of includes due to its pervasive use
-in our plugin architecture.
-
-Pros and Cons
--------------
-
-We will assume that user-based extensions will be included by them.
-
-Conditional includes:
-  Pros:
-    - User management is simplified; only a single directive needs to be set
-    - Only necessary code is included
-  Cons:
-    - Doesn't play nicely with opcode caches
-    - Adds complexity to standalone version
-    - Optional configuration directives are not exposed without a little
-      extra coaxing (not implemented yet)
-
-Include it all:
-  Pros:
-    - User management is still simple
-    - Plays nicely with opcode caches and standalone version
-    - All configuration directives are present
-  Cons:
-    - Lots of (how much?) extra code is included
-    - Classes that inherit from external libraries will cause compile
-      errors
-
-Build an include stub (Let's do this!):
-  Pros:
-    - Only necessary code is included
-    - Plays nicely with opcode caches and standalone version
-    - require (without once) can be used, see above
-    - Could further extend as a compilation to one file
-  Cons:
-    - Not implemented yet
-    - Requires user intervention and use of a command line script
-    - Standalone script must be chained to this
-    - More complex and compiled-language-like
-    - Requires a whole new class of system-wide configuration directives,
-      as configuration objects can be reused
-    - Determining what needs to be included can be complex (see above)
-    - No way of autodetecting dynamically instantiated classes
-    - Might be slow
-
-Include stubs
--------------
-
-This solution may be "just right" for users who are heavily oriented
-towards performance. However, there are a number of picky implementation
-details to work out beforehand.
-
-The number one concern is how to make the HTML Purifier files "work
-out of the box", while still being able to easily get them into a form
-that works with this setup. As the codebase stands right now, it would
-be necessary to strip out all of the require_once calls. The only way
-we could get rid of the require_once calls is to use __autoload or
-use the stub for all cases (which might not be a bad idea).
-
-    Aside
-    -----
-    An important thing to remember, however, is that these require_once's
-    are valuable data about what classes a file needs. Unfortunately, there's
-    no distinction between whether or not the file is needed all the time,
-    or whether or not it is one of our "optional" files. Thus, it is
-    effectively useless.
-
-    Deprecated
-    ----------
-    One of the things I'd like to do is have the code search for any classes
-    that are explicitly mentioned in the code. If a class isn't mentioned, I
-    get to assume that it is "optional," i.e. included via introspection.
-    The choice is either to use PHP's tokenizer or use regexps; regexps would
-    be faster but a tokenizer would be more correct. If this ends up being
-    unfeasible, adding dependency comments isn't a bad idea. (This could
-    even be done automatically by search/replacing require_once, although
-    we'd have to manually inspect the results for the optional requires.)
-
-    NOTE: This ends up not being necessary, as we're going to make the user
-    figure out all the extra classes they need, and only include the core
-    which is predetermined.
-
-Using the autoload framework with include stubs works nicely with
-introspective classes: instead of having to have require_once inside
-the function, we can let autoload do the work; we simply need to
-new $class or accept the object straight from the caller. Handling filters
-becomes a simple matter of ticking off configuration directives, and
-if ConfigSchema spits out errors, adding the necessary includes. We could
-also use the autoload framework as a fallback, in case the user forgets
-to make the include, but doesn't really care about performance.
-
-    Insight
-    -------
-    All of this talk is merely a natural extension of what our current
-    standalone functionality does. However, instead of having our code
-    perform the includes, or attempting to inline everything that possibly
-    could be used, we boot the issue to the user, making them include
-    everything or setup the fallback autoload handler.
-
-Configuration Schema
---------------------
-
-A common deficiency for all of the conditional include setups (including
-the dynamically built include PHP stub) is that if one of this
-conditionally included files includes a configuration directive, it
-is not accessible to configdoc. A stopgap solution for this problem is
-to have it piggy-back off of the data in the merge-library.php script
-to figure out what extra files it needs to include, but if the file also
-inherits classes that don't exist, we're in big trouble.
-
-I think it's high time we centralized the configuration documentation.
-However, the type checking has been a great boon for the library, and
-I'd like to keep that. The compromise is to use some other source, and
-then parse it into the ConfigSchema internal format (sans all of those
-nasty documentation strings which we really don't need at runtime) and
-serialize that for future use.
-
-The next question is that of format. XML is very verbose, and the prospect
-of setting defaults in it gives me willies. However, this may be necessary.
-Splitting up the file into manageable chunks may alleviate this trouble,
-and we may be even want to create our own format optimized for specifying
-configuration. It might look like (based off the PHPT format, which is
-nicely compact yet unambiguous and human-readable):
-
-Core.HiddenElements
-TYPE:    lookup
-DEFAULT: array('script', 'style') // auto-converted during processing
---ALIASES--
-Core.InvisibleElements, Core.StupidElements
---DESCRIPTION--
-<p>
-  Blah blah
-</p>
-
-The first line is the directive name, the lines after that prior to the
-first --HEADER-- block are single-line values, and then after that
-the multiline values are there. No value is restricted to a particular
-format: DEFAULT could very well be multiline if that would be easier.
-This would make it insanely easy, also, to add arbitrary extra parameters,
-like:
-
-VERSION:  3.0.0
-ALLOWED:  'none', 'light', 'medium', 'heavy' // this is wrapped in array()
-EXTERNAL: CSSTidy // this would be documented somewhere else with a URL
-
-The final loss would be that you wouldn't know what file the directive
-was used in; with some clever regexps it should be possible to
-figure out where $config->get($ns, $d); occurs. Reflective calls to
-the configuration object is mitigated by the fact that getBatch is
-used, so we can simply talk about that in the namespace definition page.
-This might be slow, but it would only happen when we are creating
-the documentation for consumption, and is sugar.
-
-We can put this in a schema/ directory, outside of HTML Purifier. The serialized
-data gets treated like entities.ser.
-
-The final thing that needs to be handled is user defined configurations.
-They can be added at runtime using ConfigSchema::registerDirectory()
-which globs the directory and grabs all of the directives to be incorporated
-in. Then, the result is saved. We may want to take advantage of the
-DefinitionCache framework, although it is not altogether certain what
-configuration directives would be used to generate our key (meta-directives!)
-
-    Further thoughts
-    ----------------
-    Our master configuration schema will only need to be updated once
-    every new version, so it's easily versionable. User specified
-    schema files are far more volatile, but it's far too expensive
-    to check the filemtimes of all the files, so a DefinitionRev style
-    mechanism works better. However, we can uniquely identify the
-    schema based on the directories they loaded, so there's no need
-    for a DefinitionId until we give them full programmatic control.
-
-    These variables should be directly incorporated into ConfigSchema,
-    and ConfigSchema should handle serialization. Some refactoring will be
-    necessary for the DefinitionCache classes, as they are built with
-    Config in mind. If the user changes something, the cache file gets
-    rebuilt. If the version changes, the cache file gets rebuilt. Since
-    our unit tests flush the caches before we start, and the operation is
-    pretty fast, this will not negatively impact unit testing.
-
-One last thing: certain configuration directives require that files
-get added. They may even be specified dynamically. It is not a good idea
-for the HTMLPurifier_Config object to be used directly for such matters.
-Instead, the userland code should explicitly perform the includes. We may
-put in something like:
-
-REQUIRES: HTMLPurifier_Filter_ExtractStyleBlocks
-
-To indicate that if that class doesn't exist, and the user is attempting
-to use the directive, we should fatally error out. The stub includes the core files,
-and the user includes everything else. Any reflective things like new
-$class would be required to tie in with the configuration.
-
-It would work very well with rarely used configuration options, but it
-wouldn't be so good for "core" parts that can be disabled. In such cases
-the core include file would need to be modified, and the only way
-to properly do this is use the configuration object. Once again, our
-ability to create cache keys saves the day again: we can create arbitrary
-stub files for arbitrary configurations and include those. They could
-even be the single file affairs. The only thing we'd need to include,
-then, would be HTMLPurifier_Config! Then, the configuration object would
-load the library.
-
-    An aside...
-    -----------
-    One questions, however, the wisdom of letting PHP files write other PHP
-    files. It seems like a recipe for disaster, or at least lots of headaches
-    in highly secured setups, where PHP does not have the ability to write
-    to its root. In such cases, we could use sticky bits or tell the user
-    to manually generate the file.
-
-    The other troublesome bit is actually doing the calculations necessary.
-    For certain cases, it's simple (such as URIScheme), but for AttrDef
-    and HTMLModule the dependency trees are very complex in relation to
-    %HTML.Allowed and friends. I think that this idea should be shelved
-    and looked at a later, less insane date.
-
-An interesting dilemma presents itself when a configuration form is offered
-to the user. Normally, the configuration object is not accessible without
-editing PHP code; this facility changes thing. The sensible thing to do
-is stipulate that all classes required by the directives you allow must
-be included.
-
-Unit testing
-------------
-
-Setting up the parsing and translation into our existing format would not
-be difficult to do. It might represent a good time for us to rethink our
-tests for these facilities; as creative as they are, they are often hacky
-and require public visibility for things that ought to be protected.
-This is especially applicable for our DefinitionCache tests.
-
-Migration
----------
-
-Because we are not *adding* anything essentially new, it should be trivial
-to write a script to take our existing data and dump it into the new format.
-Well, not trivial, but fairly easy to accomplish. Primary implementation
-difficulties would probably involve formatting the file nicely.
-
-Backwards-compatibility
------------------------
-
-I expect that the ConfigSchema methods should stick around for a little bit,
-but display E_USER_NOTICE warnings that they are deprecated. This will
-require documentation!
-
-New stuff
----------
-
-VERSION: Version number directive was introduced
-DEPRECATED-VERSION: If the directive was deprecated, when was it deprecated?
-DEPRECATED-USE: If the directive was deprecated, what should the user use now?
-REQUIRES: What classes does this configuration directive require, but are
-    not part of the HTML Purifier core?

-<p>
-  HTML Purifier has this quirk where if you try to allow certain elements or
-  attributes, HTML Purifier will tell you that it's not supported, and that
-  you should go to the forums to find out how to implement it. Well, this
-  document is how to implement elements and attributes which HTML Purifier
-  doesn't support out of the box.
-</p>
-
-<h2>Is it necessary?</h2>
-
-<p>
-  Before we even write any code, it is paramount to consider whether or
-  not the code we're writing is necessary or not. HTML Purifier, by default,
-  contains a large set of elements and attributes: large enough so that
-  <em>any</em> element or attribute in XHTML 1.0 or 1.1 (and its HTML variants)
-  that can be safely used by the general public is implemented.
-</p>
-
-<p>
-  So what needs to be implemented? (Feel free to skip this section if
-  you know what you want).
-</p>
-
-<h3>XHTML 1.0</h3>
-
-<p>
-  All of the modules listed below are based off of the
-  <a href="http://www.w3.org/TR/2001/REC-xhtml-modularization-20010410/abstract_modules.html#sec_5.2.">modularization of
-  XHTML</a>, which, while technically for XHTML 1.1, is quite a useful
-  resource.
-</p>
-
-<ul>
-  <li>Structure</li>
-  <li>Frames</li>
-  <li>Applets (deprecated)</li>
-  <li>Forms</li>
-  <li>Image maps</li>
-  <li>Objects</li>
-  <li>Frames</li>
-  <li>Events</li>
-  <li>Meta-information</li>
-  <li>Style sheets</li>
-  <li>Link (not hypertext)</li>
-  <li>Base</li>
-  <li>Name</li>
-</ul>
-
-<p>
-  If you don't recognize it, you probably don't need it. But the curious
-  can look all of these modules up in the above-mentioned document.  Note
-  that inline scripting comes packaged with HTML Purifier (more on this
-  later).
-</p>
-
-<h3>XHTML 1.1</h3>
-
-<p>
-  As of HTMLPurifier 2.1.0, we have implemented the
-  <a href="http://www.w3.org/TR/2001/REC-ruby-20010531/">Ruby module</a>,
-  which defines a set of tags
-  for publishing short annotations for text, used mostly in Japanese
-  and Chinese school texts, but applicable for positioning any text (not
-  limited to translations) above or below other corresponding text.
-</p>
-
-<h3>HTML 5</h3>
-
-<p>
-  <a href="http://www.whatwg.org/specs/web-apps/current-work/">HTML 5</a>
-  is a fork of HTML 4.01 by WHATWG, who believed that XHTML 2.0 was headed
-  in the wrong direction.  It too is a working draft, and may change
-  drastically before publication, but it should be noted that the
-  <code>canvas</code> tag has been implemented by many browser vendors.
-</p>
-
-<h3>Proprietary</h3>
-
-<p>
-  There are a number of proprietary tags still in the wild. Many of them
-  have been documented in <a href="ref-proprietary-tags.txt">ref-proprietary-tags.txt</a>,
-  but there is currently no implementation for any of them.
-</p>
-
-<h3>Extensions</h3>
-
-<p>
-  There are also a number of other XML languages out there that can
-  be embedded in HTML documents: two of the most popular are MathML and
-  SVG, and I frequently get requests to implement these.  But they are
-  expansive, comprehensive specifications, and it would take far too long
-  to implement them <em>correctly</em> (most systems I've seen go as far
-  as whitelisting tags and no further; come on, what about nesting!)
-</p>
-
-<p>
-  Word of warning: HTML Purifier is currently <em>not</em> namespace
-  aware.
-</p>
-
-<h2>Giving back</h2>
-
-<p>
-  As you may imagine from the details above (don't be abashed if you didn't
-  read it all: a glance over would have done), there's quite a bit that
-  HTML Purifier doesn't implement.  Recent architectural changes have
-  allowed HTML Purifier to implement elements and attributes that are not
-  safe!  Don't worry, they won't be activated unless you set %HTML.Trusted
-  to true, but they certainly help out users who need to put, say, forms
-  on their page and don't want to go through the trouble of reading this
-  and implementing it themself.
-</p>
-
-<p>
-  So any of the above that you implement for your own application could
-  help out some other poor sap on the other side of the globe.  Help us
-  out, and send back code so that it can be hammered into a module and
-  released with the core.  Any code would be greatly appreciated!
-</p>
-
-<h2>And now...</h2>
-
-<p>
-  Enough philosophical talk, time for some code:
-</p>
-
-<pre>$config = HTMLPurifier_Config::createDefault();
-$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
-$config-&gt;set('HTML.DefinitionRev', 1);
-$def = $config-&gt;getHTMLDefinition(true);</pre>
-
-<p>
-  Assuming that HTML Purifier has already been properly loaded (hint:
-  include <code>HTMLPurifier.auto.php</code>), this code will set up
-  the environment that you need to start customizing the HTML definition.
-  What's going on?
-</p>
-
-<ul>
-  <li>
-    The first three lines are regular configuration code:
-    <ul>
-      <li>
-        %HTML.DefinitionID is set to a unique identifier for your
-        custom HTML definition.  This prevents it from clobbering
-        other custom definitions on the same installation.
-      </li>
-      <li>
-        %HTML.DefinitionRev is a revision integer of your HTML
-        definition.  Because HTML definitions are cached, you'll need
-        to increment this whenever you make a change in order to flush
-        the cache.
-      </li>
-    </ul>
-  </li>
-  <li>
-    The fourth line retrieves a raw <code>HTMLPurifier_HTMLDefinition</code>
-    object that we will be tweaking. If the parameter was removed, we
-    would be retrieving a fully formed definition object, which is somewhat
-    useless for customization purposes.
-  </li>
-</ul>
-
-<h3>Broken backwards-compatibility</h3>
-
-<p>
-  Those of you who have already been twiddling around with the raw
-  HTML definition object, you'll be noticing that you're getting an error
-  when you attempt to retrieve the raw definition object without specifying
-  a DefinitionID.  It is vital to caching (see below) that you make a unique
-  name for your customized definition, so make up something right now and
-  things will operate again.
-</p>
-
-<h2>Turn off caching</h2>
-
-<p>
-  To make development easier, we're going to temporarily turn off
-  definition caching:
-</p>
-
-<pre>$config = HTMLPurifier_Config::createDefault();
-$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
-$config-&gt;set('HTML.DefinitionRev', 1);
-<strong>$config-&gt;set('Cache.DefinitionImpl', null); // TODO: remove this later!</strong>
-$def = $config-&gt;getHTMLDefinition(true);</pre>
-
-<p>
-  A few things should be mentioned about the caching mechanism before
-  we move on.  For performance reasons, HTML Purifier caches generated
-  <code>HTMLPurifier_Definition</code> objects in serialized files
-  stored (by default) in <code>library/HTMLPurifier/DefinitionCache/Serializer</code>.
-  A lot of processing is done in order to create these objects, so it
-  makes little sense to repeat the same processing over and over again
-  whenever HTML Purifier is called.
-</p>
-
-<p>
-  In order to identify a cache entry, HTML Purifier uses three variables:
-  the library's version number, the value of %HTML.DefinitionRev and
-  a serial of relevant configuration.  Whenever any of these changes,
-  a new HTML definition is generated.  Notice that there is no way
-  for the definition object to track changes to customizations: here, it
-  is up to you to supply appropriate information to DefinitionID and
-  DefinitionRev.
-</p>
-
-<h2 id="addAttribute">Add an attribute</h2>
-
-<p>
-  For this example, we're going to implement the <code>target</code> attribute found
-  on <code>a</code> elements.  To implement an attribute, we have to
-  ask a few questions:
-</p>
-
-<ol>
-  <li>What element is it found on?</li>
-  <li>What is its name?</li>
-  <li>Is it required or optional?</li>
-  <li>What are valid values for it?</li>
-</ol>
-
-<p>
-  The first three are easy: the element is <code>a</code>, the attribute
-  is <code>target</code>, and it is not a required attribute. (If it
-  was required, we'd need to append an asterisk to the attribute name,
-  you'll see an example of this in the addElement() example).
-</p>
-
-<p>
-  The last question is a little trickier.
-  Lets allow the special values: _blank, _self, _target and _top.
-  The form of this is called an <strong>enumeration</strong>, a list of
-  valid values, although only one can be used at a time.  To translate
-  this into code form, we write:
-</p>
-
-<pre>$config = HTMLPurifier_Config::createDefault();
-$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
-$config-&gt;set('HTML.DefinitionRev', 1);
-$config-&gt;set('Cache.DefinitionImpl', null); // remove this later!
-$def = $config-&gt;getHTMLDefinition(true);
-<strong>$def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');</strong></pre>
-
-<p>
-  The <code>Enum#_blank,_self,_target,_top</code> does all the magic.
-  The string is split into two parts, separated by a hash mark (#):
-</p>
-
-<ol>
-  <li>The first part is the name of what we call an <code>AttrDef</code></li>
-  <li>The second part is the parameter of the above-mentioned <code>AttrDef</code></li>
-</ol>
-
-<p>
-  If that sounds vague and generic, it's because it is!  HTML Purifier defines
-  an assortment of different attribute types one can use, and each of these
-  has their own specialized parameter format.  Here are some of the more useful
-  ones:
-</p>
-
-<table class="table">
-  <thead>
-    <tr>
-      <th>Type</th>
-      <th>Format</th>
-      <th>Description</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <th>Enum</th>
-      <td><em>[s:]</em>value1,value2,...</td>
-      <td>
-        Attribute with a number of valid values, one of which may be used. When
-        s: is present, the enumeration is case sensitive.
-      </td>
-    </tr>
-    <tr>
-      <th>Bool</th>
-      <td>attribute_name</td>
-      <td>
-        Boolean attribute, with only one valid value: the name
-        of the attribute.
-      </td>
-    </tr>
-    <tr>
-      <th>CDATA</th>
-      <td></td>
-      <td>
-        Attribute of arbitrary text. Can also be referred to as <strong>Text</strong>
-        (the specification makes a semantic distinction between the two).
-      </td>
-    </tr>
-    <tr>
-      <th>ID</th>
-      <td></td>
-      <td>
-        Attribute that specifies a unique ID
-      </td>
-    </tr>
-    <tr>
-      <th>Pixels</th>
-      <td></td>
-      <td>
-        Attribute that specifies an integer pixel length
-      </td>
-    </tr>
-    <tr>
-      <th>Length</th>
-      <td></td>
-      <td>
-        Attribute that specifies a pixel or percentage length
-      </td>
-    </tr>
-    <tr>
-      <th>NMTOKENS</th>
-      <td></td>
-      <td>
-        Attribute that specifies a number of name tokens, example: the
-        <code>class</code> attribute
-      </td>
-    </tr>
-    <tr>
-      <th>URI</th>
-      <td></td>
-      <td>
-        Attribute that specifies a URI, example: the <code>href</code>
-        attribute
-      </td>
-    </tr>
-    <tr>
-      <th>Number</th>
-      <td></td>
-      <td>
-        Attribute that specifies an positive integer number
-      </td>
-    </tr>
-  </tbody>
-</table>
-
-<p>
-  For a complete list, consult
-  <a href="http://repo.or.cz/w/htmlpurifier.git?a=blob;hb=HEAD;f=library/HTMLPurifier/AttrTypes.php"><code>library/HTMLPurifier/AttrTypes.php</code></a>;
-  more information on attributes that accept parameters can be found on their
-  respective includes in
-  <a href="http://repo.or.cz/w/htmlpurifier.git?a=tree;hb=HEAD;f=library/HTMLPurifier/AttrDef"><code>library/HTMLPurifier/AttrDef</code></a>.
-</p>
-
-<p>
-  Sometimes, the restrictive list in AttrTypes just doesn't cut it. Don't
-  sweat: you can also use a fully instantiated object as the value. The
-  equivalent, verbose form of the above example is:
-</p>
-
-<pre>$config = HTMLPurifier_Config::createDefault();
-$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
-$config-&gt;set('HTML.DefinitionRev', 1);
-$config-&gt;set('Cache.DefinitionImpl', null); // remove this later!
-$def = $config-&gt;getHTMLDefinition(true);
-<strong>$def-&gt;addAttribute('a', 'target', new HTMLPurifier_AttrDef_Enum(
-  array('_blank','_self','_target','_top')
-));</strong></pre>
-
-<p>
-  Trust me, you'll learn to love the shorthand.
-</p>
-
-<h2>Add an element</h2>
-
-<p>
-  Adding attributes is really small-fry stuff, though, and it was possible
-  to add them (albeit a bit more wordy) prior to 2.0. The real gem of
-  the Advanced API is adding elements. There are five questions to
-  ask when adding a new element:
-</p>
-
-<ol>
-  <li>What is the element's name?</li>
-  <li>What content set does this element belong to?</li>
-  <li>What are the allowed children of this element?</li>
-  <li>What attributes does the element allow that are general?</li>
-  <li>What attributes does the element allow that are specific to this element?</li>
-</ol>
-
-<p>
-  It's a mouthful, and you'll be slightly lost if your not familiar with
-  the HTML specification, so let's explain them step by step.
-</p>
-
-<h3>Content set</h3>
-
-<p>
-  The HTML specification defines two major content sets: Inline
-  and Block.  Each of these
-  content sets contain a list of elements: Inline contains things like
-  <code>span</code> and <code>b</code> while Block contains things like
-  <code>div</code> and <code>blockquote</code>.
-</p>
-
-<p>
-  These content sets amount to a macro mechanism for HTML definition. Most
-  elements in HTML are organized into one of these two sets, and most
-  elements in HTML allow elements from one of these sets.  If we had
-  to write each element verbatim into each other element's allowed
-  children, we would have ridiculously large lists; instead we use
-  content sets to compactify the declaration.
-</p>
-
-<p>
-  Practically speaking, there are several useful values you can use here:
-</p>
-
-<table class="table">
-  <thead>
-    <tr>
-      <th>Content set</th>
-      <th>Description</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <th>Inline</th>
-      <td>Character level elements, text</td>
-    </tr>
-    <tr>
-      <th>Block</th>
-      <td>Block-like elements, like paragraphs and lists</td>
-    </tr>
-    <tr>
-      <th><em>false</em></th>
-      <td>
-        Any element that doesn't fit into the mold, for example <code>li</code>
-        or <code>tr</code>
-      </td>
-    </tr>
-  </tbody>
-</table>
-
-<p>
-  By specifying a valid value here, all other elements that use that
-  content set will also allow your element, without you having to do
-  anything. If you specify <em>false</em>, you'll have to register
-  your element manually.
-</p>
-
-<h3>Allowed children</h3>
-
-<p>
-  Allowed children defines the elements that this element can contain.
-  The allowed values may range from none to a complex regexp depending on
-  your element.
-</p>
-
-<p>
-  If you've ever taken a look at the HTML DTD's before, you may have
-  noticed declarations like this:
-</p>
-
-<pre>&lt;!ELEMENT LI - O (%flow;)*             -- list item --&gt;</pre>
-
-<p>
-  The <code>(%flow;)*</code> indicates the allowed children of the
-  <code>li</code> tag: <code>li</code> allows any number of flow
-  elements as its children. (The <code>- O</code> allows the closing tag to be
-  omitted, though in XML this is not allowed.) In HTML Purifier,
-  we'd write it like <code>Flow</code> (here's where the content sets
-  we were discussing earlier come into play). There are three shorthand
-  content models you can specify:
-</p>
-
-<table class="table">
-  <thead>
-    <tr>
-      <th>Content model</th>
-      <th>Description</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <th>Empty</th>
-      <td>No children allowed, like <code>br</code> or <code>hr</code></td>
-    </tr>
-    <tr>
-      <th>Inline</th>
-      <td>Any number of inline elements and text, like <code>span</code></td>
-    </tr>
-    <tr>
-      <th>Flow</th>
-      <td>Any number of inline elements, block elements and text, like <code>div</code></td>
-    </tr>
-  </tbody>
-</table>
-
-<p>
-  This covers 90% of all the cases out there, but what about elements that
-  break the mold like <code>ul</code>? This guy requires at least one
-  child, and the only valid children for it are <code>li</code>. The
-  content model is: <code>Required: li</code>. There are two parts: the
-  first type determines what <code>ChildDef</code> will be used to validate
-  content models. The most common values are:
-</p>
-
-<table class="table">
-  <thead>
-    <tr>
-      <th>Type</th>
-      <th>Description</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <th>Required</th>
-      <td>Children must be one or more of the valid elements</td>
-    </tr>
-    <tr>
-      <th>Optional</th>
-      <td>Children can be any number of the valid elements</td>
-    </tr>
-    <tr>
-      <th>Custom</th>
-      <td>Children must follow the DTD-style regex</td>
-    </tr>
-  </tbody>
-</table>
-
-<p>
-  You can also implement your own <code>ChildDef</code>: this was done
-  for a few special cases in HTML Purifier such as <code>Chameleon</code>
-  (for <code>ins</code> and <code>del</code>), <code>StrictBlockquote</code>
-  and <code>Table</code>.
-</p>
-
-<p>
-  The second part specifies either valid elements or a regular expression.
-  Valid elements are separated with horizontal bars (|), i.e.
-  "<code>a | b | c</code>".  Use #PCDATA to represent plain text.
-  Regular expressions are based off of DTD's style:
-</p>
-
-<ul>
-  <li>Parentheses () are used for grouping</li>
-  <li>Commas (,) separate elements that should come one after another</li>
-  <li>Horizontal bars (|) indicate one or the other elements should be used</li>
-  <li>Plus signs (+) are used for a one or more match</li>
-  <li>Asterisks (*) are used for a zero or more match</li>
-  <li>Question marks (?) are used for a zero or one match</li>
-</ul>
-
-<p>
-  For example, "<code>a, b?, (c | d), e+, f*</code>" means "In this order,
-  one <code>a</code> element, at most one <code>b</code> element,
-  one <code>c</code> or <code>d</code> element (but not both), one or more
-  <code>e</code> elements, and any number of <code>f</code> elements."
-  Regex veterans should be able to jump right in, and those not so savvy
-  can always copy-paste W3C's content model definitions into HTML Purifier
-  and hope for the best.
-</p>
-
-<p>
-  A word of warning: while the regex format is extremely flexible on
-  the developer's side, it is
-  quite unforgiving on the user's side.  If the user input does not <em>exactly</em>
-  match the specification, the entire contents of the element will
-  be nuked.  This is why there is are specific content model types like
-  Optional and Required: while they could be implemented as <code>Custom:
-  (valid | elements)*</code>, the custom classes contain special recovery
-  measures that make sure as much of the user's original content gets
-  through. HTML Purifier's core, as a rule, does not use Custom.
-</p>
-
-<p>
-  One final note: you can also use Content Sets inside your valid elements
-  lists or regular expressions. In fact, the three shorthand content models
-  mentioned above are just that: abbreviations:
-</p>
-
-<table class="table">
-  <thead>
-    <tr>
-      <th>Content model</th>
-      <th>Implementation</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <th>Inline</th>
-      <td>Optional: Inline | #PCDATA</td>
-    </tr>
-    <tr>
-      <th>Flow</th>
-      <td>Optional: Flow | #PCDATA</td>
-    </tr>
-  </tbody>
-</table>
-
-<p>
-  When the definition is compiled, Inline will be replaced with a
-  horizontal-bar separated list of inline elements. Also, notice that
-  it does not contain text: you have to specify that yourself.
-</p>
-
-<h3>Common attributes</h3>
-
-<p>
-  Congratulations: you have just gotten over the proverbial hump (Allowed
-  children). Common attributes is much simpler, and boils down to
-  one question: does your element have the <code>id</code>, <code>style</code>,
-  <code>class</code>, <code>title</code> and <code>lang</code> attributes?
-  If so, you'll want to specify the <code>Common</code> attribute collection,
-  which contains these five attributes that are found on almost every
-  HTML element in the specification.
-</p>
-
-<p>
-  There are a few more collections, but they're really edge cases:
-</p>
-
-<table class="table">
-  <thead>
-    <tr>
-      <th>Collection</th>
-      <th>Attributes</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <th>I18N</th>
-      <td><code>lang</code>, possibly <code>xml:lang</code></td>
-    </tr>
-    <tr>
-      <th>Core</th>
-      <td><code>style</code>, <code>class</code>, <code>id</code> and <code>title</code></td>
-    </tr>
-  </tbody>
-</table>
-
-<p>
-  Common is a combination of the above-mentioned collections.
-</p>
-
-<p class="aside">
-  Readers familiar with the modularization may have noticed that the Core
-  attribute collection differs from that specified by the <a
-  href="http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_commonatts">abstract
-  modules of the XHTML Modularization 1.1</a>. We believe this section
-  to be in error, as <code>br</code> permits the use of the <code>style</code>
-  attribute even though it uses the <code>Core</code> collection, and
-  the DTD and XML Schemas supplied by W3C support our interpretation.
-</p>
-
-<h3>Attributes</h3>
-
-<p>
-  If you didn't read the <a href="#addAttribute">earlier section on
-  adding attributes</a>, read it now.  The last parameter is simply
-  an array of attribute names to attribute implementations, in the exact
-  same format as <code>addAttribute()</code>.
-</p>
-
-<h3>Putting it all together</h3>
-
-<p>
-  We're going to implement <code>form</code>. Before we embark, lets
-  grab a reference implementation from over at the
-  <a href="http://www.w3.org/TR/html4/sgml/loosedtd.html">transitional DTD</a>:
-</p>
-
-<pre>&lt;!ELEMENT FORM - - (%flow;)* -(FORM)   -- interactive form --&gt;
-&lt;!ATTLIST FORM
-  %attrs;                              -- %coreattrs, %i18n, %events --
-  action      %URI;          #REQUIRED -- server-side form handler --
-  method      (GET|POST)     GET       -- HTTP method used to submit the form--
-  enctype     %ContentType;  &quot;application/x-www-form-urlencoded&quot;
-  accept      %ContentTypes; #IMPLIED  -- list of MIME types for file upload --
-  name        CDATA          #IMPLIED  -- name of form for scripting --
-  onsubmit    %Script;       #IMPLIED  -- the form was submitted --
-  onreset     %Script;       #IMPLIED  -- the form was reset --
-  target      %FrameTarget;  #IMPLIED  -- render in this frame --
-  accept-charset %Charsets;  #IMPLIED  -- list of supported charsets --
-  &gt;</pre>
-
-<p>
-  Juicy! With just this, we can answer four of our five questions:
-</p>
-
-<ol>
-  <li>What is the element's name? <strong>form</strong></li>
-  <li>What content set does this element belong to? <strong>Block</strong>
-    (this needs a little sleuthing, I find the easiest way is to search
-    the DTD for <code>FORM</code> and determine which set it is in.)</li>
-  <li>What are the allowed children of this element? <strong>One
-    or more flow elements, but no nested <code>form</code>s</strong></li>
-  <li>What attributes does the element allow that are general? <strong>Common</strong></li>
-  <li>What attributes does the element allow that are specific to this element? <strong>A whole bunch, see ATTLIST;
-    we're going to do the vital ones: <code>action</code>, <code>method</code> and <code>name</code></strong></li>
-</ol>
-
-<p>
-  Time for some code:
-</p>
-
-<pre>$config = HTMLPurifier_Config::createDefault();
-$config-&gt;set('HTML.DefinitionID', 'enduser-customize.html tutorial');
-$config-&gt;set('HTML.DefinitionRev', 1);

-
-<p>
-  Each of the parameters corresponds to one of the questions we asked.
-  Notice that we added an asterisk to the end of the <code>action</code>
-  attribute to indicate that it is required. If someone specifies a
-  <code>form</code> without that attribute, the tag will be axed.
-  Also, the extra line at the end is a special extra declaration that
-  prevents forms from being nested within each other.
-</p>
-
-<p>
-  And that's all there is to it! Implementing the rest of the form
-  module is left as an exercise to the user; to see more examples

-  in your local HTML Purifier installation.

-
-<h2>And beyond...</h2>
-
-<p>
-  Perceptive users may have realized that, to a certain extent, we
-  have simply re-implemented the facilities of XML Schema or the
-  Document Type Definition.  What you are seeing here, however, is
-  not just an XML Schema or Document Type Definition: it is a fully
-  expressive method of specifying the definition of HTML that is
-  a portable superset of the capabilities of the two above-mentioned schema
-  languages.  What makes HTMLDefinition so powerful is the fact that
-  if we don't have an implementation for a content model or an attribute
-  definition, you can supply it yourself by writing a PHP class.

-
-<p>HTML Purifier is a very powerful library. But with power comes great
-responsibility, in the form of longer execution times.  Remember, this
-library isn't lightly grazing over submitted HTML: it's deconstructing
-the whole thing, rigorously checking the parts, and then putting it back
-together. </p>
-
-<p>So, if it so turns out that HTML Purifier is kinda too slow for outbound
-filtering, you've got a few options: </p>
-
-<h2>Inbound filtering</h2>
-
-<p>Perform filtering of HTML when it's submitted by the user. Since the
-user is already submitting something, an extra half a second tacked on
-to the load time probably isn't going to be that huge of a problem.
-Then, displaying the content is a simple a manner of outputting it
-directly from your database/filesystem. The trouble with this method is
-that your user loses the original text, and when doing edits, will be
-handling the filtered text.  While this may be a good thing, especially
-if you're using a WYSIWYG editor, it can also result in data-loss if a
-user makes a typo. </p>
-
-<p>Example (non-functional):</p>
-
-<pre>&lt;?php
-    /**
-     * FORM SUBMISSION PAGE
-     * display_error($message) : displays nice error page with message
-     * display_success() : displays a nice success page
-     * display_form() : displays the HTML submission form
-     * database_insert($html) : inserts data into database as new row
-     */
-    if (!empty($_POST)) {
-        require_once '/path/to/library/HTMLPurifier.auto.php';
-        require_once 'HTMLPurifier.func.php';
-        $dirty_html = isset($_POST['html']) ? $_POST['html'] : false;
-        if (!$dirty_html) {
-            display_error('You must write some HTML!');
-        }
-        $html = HTMLPurifier($dirty_html);
-        database_insert($html);
-        display_success();
-        // notice that $dirty_html is *not* saved
-    } else {
-        display_form();
-    }
-?&gt;</pre>
-
-<h2>Caching the filtered output</h2>
-
-<p>Accept the submitted text and put it unaltered into the database, but
-then also generate a filtered version and stash that in the database.
-Serve the filtered version to readers, and the unaltered version to
-editors.  If need be, you can invalidate the cache and have the cached
-filtered version be regenerated on the first page view.  Pros? Full data
-retention. Cons? It's more complicated, and opens other editors up to
-XSS if they are using a WYSIWYG editor (to fix that, they'd have to be
-able to get their hands on the *really* original text served in
-plaintext mode). </p>
-
-<p>Example (non-functional):</p>
-
-<pre>&lt;?php
-    /**
-     * VIEW PAGE
-     * display_error($message) : displays nice error page with message
-     * cache_get($id) : retrieves HTML from fast cache (db or file)
-     * cache_insert($id, $html) : inserts good HTML into cache system
-     * database_get($id) : retrieves raw HTML from database
-     */
-    $id = isset($_GET['id']) ? (int) $_GET['id'] : false;
-    if (!$id) {
-        display_error('Must specify ID.');
-        exit;
-    }
-    $html = cache_get($id); // filesystem or database
-    if ($html === false) {
-        // cache didn't have the HTML, generate it
-        $raw_html = database_get($id);
-        require_once '/path/to/library/HTMLPurifier.auto.php';
-        require_once 'HTMLPurifier.func.php';
-        $html = HTMLPurifier($raw_html);
-        cache_insert($id, $html);
-    }
-    echo $html;
-?&gt;</pre>
-
-<h2>Summary</h2>
-
-<p>In short, inbound filtering is the simple option and caching is the
-robust option (albeit with bigger storage requirements). </p>
-
-<p>There is a third option, independent of the two we've discussed: profile
-and optimize HTMLPurifier yourself. Be sure to report back your results
-if you decide to do that! Especially if you port HTML Purifier to C++.

-<p>You've probably heard of HTML Tidy, Dave Raggett's little piece
-of software that cleans up poorly written HTML.  Let me say it straight
-out:</p>
-
-<p class="emphasis">This ain't HTML Tidy!</p>
-
-<p>Rather, Tidy stands for a cool set of Tidy-inspired features in HTML Purifier
-that allows users to submit deprecated elements and attributes and get
-valid strict markup back. For example:</p>
-
-<pre>&lt;center&gt;Centered&lt;/center&gt;</pre>
-
-<p>...becomes:</p>
-
-<pre>&lt;div style=&quot;text-align:center;&quot;&gt;Centered&lt;/div&gt;</pre>
-
-<p>...when this particular fix is run on the HTML. This tutorial will give
-you the lowdown of what exactly HTML Purifier will do when Tidy
-is on, and how to fine-tune this behavior. Once again, <strong>you do
-not need Tidy installed on your PHP to use these features!</strong></p>
-
-<h2>What does it do?</h2>
-
-<p>Tidy will do several things to your HTML:</p>
-
-<ul>
-    <li>Convert deprecated elements and attributes to standards-compliant
-        alternatives</li>
-    <li>Enforce XHTML compatibility guidelines and other best practices</li>
-    <li>Preserve data that would normally be removed as per W3C</li>
-</ul>
-
-<h2>What are levels?</h2>
-
-<p>Levels describe how aggressive the Tidy module should be when
-cleaning up HTML. There are four levels to pick: none, light, medium
-and heavy. Each of these levels has a well-defined set of behavior
-associated with it, although it may change depending on your doctype.</p>
-
-<dl>
-    <dt>light</dt>
-    <dd>This is the <strong>lenient</strong> level. If a tag or attribute
-        is about to be removed because it isn't supported by the
-        doctype, Tidy will step in and change into an alternative that
-        is supported.</dd>
-    <dt>medium</dt>
-    <dd>This is the <strong>correctional</strong> level. At this level,
-        all the functions of light are performed, as well as some extra,
-        non-essential best practices enforcement. Changes made on this
-        level are very benign and are unlikely to cause problems.</dd>
-    <dt>heavy</dt>
-    <dd>This is the <strong>aggressive</strong> level. If a tag or
-        attribute is deprecated, it will be converted into a non-deprecated
-        version, no ifs ands or buts.</dd>
-</dl>
-
-<p>By default, Tidy operates on the <strong>medium</strong> level. You can
-change the level of cleaning by setting the %HTML.TidyLevel configuration
-directive:</p>
-
-<pre>$config-&gt;set('HTML.TidyLevel', 'heavy'); // burn baby burn!</pre>
-
-<h2>Is the light level really light?</h2>
-
-<p>It depends on what doctype you're using. If your documents are HTML
-4.01 <em>Transitional</em>, HTML Purifier will be lazy
-and won't clean up your <code>center</code>
-or <code>font</code> tags. But if you're using HTML 4.01 <em>Strict</em>,
-HTML Purifier has no choice: it has to convert them, or they will
-be nuked out of existence. So while light on Transitional will result
-in little to no changes, light on Strict will still result in quite
-a lot of fixes.</p>
-
-<p>This is different behavior from 1.6 or before, where deprecated
-tags in transitional documents would
-always be cleaned up regardless. This is also better behavior.</p>
-
-<h2>My pages look different!</h2>
-
-<p>HTML Purifier is tasked with converting deprecated tags and
-attributes to standards-compliant alternatives, which usually
-need copious amounts of CSS. It's also not foolproof: sometimes
-things do get lost in the translation. This is why when HTML Purifier
-can get away with not doing cleaning, it won't; this is why
-the default value is <strong>medium</strong> and not heavy.</p>
-
-<p>Fortunately, only a few attributes have problems with the switch
-over. They are described below:</p>
-
-<table class="table">
-    <thead><tr>
-        <th>Element@Attr</th>
-        <th>Changes</th>
-    </tr></thead>
-    <tbody>
-        <tr>
-            <td>caption@align</td>
-            <td>Firefox supports stuffing the caption on the
-                left and right side of the table, a feature that
-                Internet Explorer, understandably, does not have.
-                When align equals right or left, the text will simply
-                be aligned on the left or right side.</td>
-        </tr>
-        <tr>
-            <td>img@align</td>
-            <td>The implementation for align bottom is good, but not
-            perfect. There are a few pixel differences.</td>
-        </tr>
-        <tr>
-            <td>br@clear</td>
-            <td>Clear both gets a little wonky in Internet Explorer. Haven't
-                really been able to figure out why.</td>
-        </tr>
-        <tr>
-            <td>hr@noshade</td>
-            <td>All browsers implement this slightly differently: we've
-                chosen to make noshade horizontal rules gray.</td>
-        </tr>
-    </tbody>
-</table>
-
-<p>There are a few more minor, although irritating, bugs.
-Some older browsers support deprecated attributes,
-but not CSS. Transformed elements and attributes will look unstyled
-to said browsers. Also, CSS precedence is slightly different for
-inline styles versus presentational markup. In increasing precedence:</p>
-
-<ol>
-    <li>Presentational attributes</li>
-    <li>External style sheets</li>
-    <li>Inline styling</li>
-</ol>
-
-<p>This means that styling that may have been masked by external CSS
-declarations will start showing up (a good thing, perhaps). Finally,
-if you've turned off the style attribute, almost all of
-these transformations will not work. Sorry mates.</p>
-
-<p>You can review the rendering before and after of these transformations
-by consulting the <a
-href="http://htmlpurifier.org/live/smoketests/attrTransform.php">attrTransform.php
-smoketest</a>.</p>
-
-<h2>I like the general idea, but the specifics bug me!</h2>
-
-<p>So you want HTML Purifier to clean up your HTML, but you're not
-so happy about the br@clear implementation. That's perfectly fine!
-HTML Purifier will make accomodations:</p>
-
-<pre>$config-&gt;set('HTML.Doctype', 'XHTML 1.0 Transitional');
-$config-&gt;set('HTML.TidyLevel', 'heavy'); // all changes, minus...
-<strong>$config-&gt;set('HTML.TidyRemove', 'br@clear');</strong></pre>
-
-<p>That third line does the magic, removing the br@clear fix
-from the module, ensuring that <code>&lt;br clear="both" /&gt;</code>
-will pass through unharmed. The reverse is possible too:</p>
-
-<pre>$config-&gt;set('HTML.Doctype', 'XHTML 1.0 Transitional');
-$config-&gt;set('HTML.TidyLevel', 'none'); // no changes, plus...
-<strong>$config-&gt;set('HTML.TidyAdd', 'p@align');</strong></pre>
-
-<p>In this case, all transformations are shut off, except for the p@align
-one, which you found handy.</p>
-
-<p>To find out what the names of fixes you want to turn on or off are,
-you'll have to consult the source code, specifically the files in
-<code>HTMLPurifier/HTMLModule/Tidy/</code>. There is, however, a
-general syntax:</p>
-
-<table class="table">
-    <thead>
-        <tr>
-            <th>Name</th>
-            <th>Example</th>
-            <th>Interpretation</th>
-        </tr>
-    </thead>
-    <tbody>
-        <tr>
-            <td>element</td>
-            <td>font</td>
-            <td>Tag transform for <em>element</em></td>
-        </tr>
-        <tr>
-            <td>element@attr</td>
-            <td>br@clear</td>
-            <td>Attribute transform for <em>attr</em> on <em>element</em></td>
-        </tr>
-        <tr>
-            <td>@attr</td>
-            <td>@lang</td>
-            <td>Global attribute transform for <em>attr</em></td>
-        </tr>
-        <tr>
-            <td>e#content_model_type</td>
-            <td>blockquote#content_model_type</td>
-            <td>Change of child processing implementation for <em>e</em></td>
-        </tr>
-    </tbody>
-</table>
-
-<h2>So... what's the lowdown?</h2>
-
-<p>The lowdown is, quite frankly, HTML Purifier's default settings are
-probably good enough. The next step is to bump the level up to heavy,
-and if that still doesn't satisfy your appetite, do some fine-tuning.
-Other than that, don't worry about it: this all works silently and
-effectively in the background.</p>

-<h1>URI Filters</h1>
-
-<div id="filing">Filed under End-User</div>

-<div id="home"><a href="http://htmlpurifier.org/">HTML Purifier</a> End-User Documentation</div>
-
-<p>
-  This is a quick and dirty document to get you on your way to writing
-  custom URI filters for your own URL filtering needs.  Why would you
-  want to write a URI filter?  If you need URIs your users put into
-  HTML to magically change into a different URI, this is
-  exactly what you need!
-</p>
-
-<h2>Creating the class</h2>
-
-<p>
-  Any URI filter you make will be a subclass of <code>HTMLPurifier_URIFilter</code>.
-  The scaffolding is thus:
-</p>
-
-<pre>class HTMLPurifier_URIFilter_<strong>NameOfFilter</strong> extends HTMLPurifier_URIFilter
-{
-    public $name = '<strong>NameOfFilter</strong>';
-    public function prepare($config) {}
-    public function filter(&$uri, $config, $context) {}
-}</pre>
-
-<p>
-  Fill in the variable <code>$name</code> with the name of your filter, and
-  take a look at the two methods. <code>prepare()</code> is an initialization
-  method that is called only once, before any filtering has been done of the
-  HTML. Use it to perform any costly setup work that only needs to be done
-  once. <code>filter()</code> is the guts and innards of our filter:
-  it takes the URI and does whatever needs to be done to it.
-</p>
-
-<p>
-  If you've worked with HTML Purifier, you'll recognize the <code>$config</code>
-  and <code>$context</code> parameters.  On the other hand, <code>$uri</code>
-  is something unique to this section of the application: it's a
-  <code>HTMLPurifier_URI</code> object. The interface is thus:
-</p>
-
-<pre>class HTMLPurifier_URI
-{
-    public $scheme, $userinfo, $host, $port, $path, $query, $fragment;
-    public function HTMLPurifier_URI($scheme, $userinfo, $host, $port, $path, $query, $fragment);
-    public function toString();
-    public function copy();
-    public function getSchemeObj($config, $context);
-    public function validate($config, $context);
-}</pre>
-
-<p>
-  The first three methods are fairly self-explanatory: you have a constructor,
-  a serializer, and a cloner.  Generally, you won't be using them when
-  you are manipulating the URI objects themselves.
-  <code>getSchemeObj()</code> is a special purpose method that returns
-  a <code>HTMLPurifier_URIScheme</code> object corresponding to the specific
-  URI at hand. <code>validate()</code> performs general-purpose validation
-  on the internal components of a URI. Once again, you don't need to
-  worry about these: they've already been handled for you.
-</p>
-
-<h2>URI format</h2>
-
-<p>
-  As a URIFilter, we're interested in the member variables of the URI object.
-</p>
-
-<table class="quick"><tbody>
-  <tr><th>Scheme</th>   <td>The protocol for identifying (and possibly locating) a resource (http, ftp, https)</td></tr>
-  <tr><th>Userinfo</th> <td>User information such as a username (bob)</td></tr>
-  <tr><th>Host</th>     <td>Domain name or IP address of the server (example.com, 127.0.0.1)</td></tr>
-  <tr><th>Port</th>     <td>Network port number for the server (80, 12345)</td></tr>
-  <tr><th>Path</th>     <td>Data that identifies the resource, possibly hierarchical (/path/to, ed@example.com)</td></tr>
-  <tr><th>Query</th>    <td>String of information to be interpreted by the resource (?q=search-term)</td></tr>
-  <tr><th>Fragment</th> <td>Additional information for the resource after retrieval (#bookmark)</td></tr>
-</tbody></table>
-
-<p>
-  Because the URI is presented to us in this form, and not
-  <code>http://bob@example.com:8080/foo.php?q=string#hash</code>, it saves us
-  a lot of trouble in having to parse the URI every time we want to filter
-  it. For the record, the above URI has the following components:
-</p>
-
-<table class="quick"><tbody>
-  <tr><th>Scheme</th>   <td>http</td></tr>
-  <tr><th>Userinfo</th> <td>bob</td></tr>
-  <tr><th>Host</th>     <td>example.com</td></tr>
-  <tr><th>Port</th>     <td>8080</td></tr>
-  <tr><th>Path</th>     <td>/foo.php</td></tr>
-  <tr><th>Query</th>    <td>q=string</td></tr>
-  <tr><th>Fragment</th> <td>hash</td></tr>
-</tbody></table>
-
-<p>
-  Note that there is no question mark or octothorpe in the query or
-  fragment: these get removed during parsing.
-</p>
-
-<p>
-  With this information, you can get straight to implementing your
-  <code>filter()</code> method. But one more thing...
-</p>
-
-<h2>Return value: Boolean, not URI</h2>
-
-<p>
-  You may have noticed that the URI is being passed in by reference.
-  This means that whatever changes you make to it, those changes will
-  be reflected in the URI object the callee had.  <strong>Do not
-  return the URI object: it is unnecessary and will cause bugs.</strong>
-  Instead, return a boolean value, true if the filtering was successful,
-  or false if the URI is beyond repair and needs to be axed.
-</p>
-
-<p>
-  Let's suppose I wanted to write a filter that converted links with a
-  custom <code>image</code> scheme to its corresponding real path on
-  our website:
-</p>
-
-<pre>class HTMLPurifier_URIFilter_TransformImageScheme extends HTMLPurifier_URIFilter
-{
-    public $name = 'TransformImageScheme';
-    public function filter(&$uri, $config, $context) {
-        if ($uri->scheme !== 'image') return true;
-        $img_name = $uri->path;
-        // Overwrite the previous URI object
-        $uri = new HTMLPurifier_URI('http', null, null, null, '/img/' . $img_name . '.png', null, null);
-        return true;
-    }
-}</pre>
-
-<p>
-  Notice I did not <code>return $uri;</code>. This filter would turn
-  <code>image:Foo</code> into <code>/img/Foo.png</code>.
-</p>
-
-<h2>Activating your filter</h2>
-
-<p>
-  Having a filter is all well and good, but you need to tell HTML Purifier
-  to use it. Fortunately, this part's simple:
-</p>
-
-<pre>$uri = $config->getDefinition('URI');
-$uri->addFilter(new HTMLPurifier_URIFilter_<strong>NameOfFilter</strong>(), $config);</pre>
-
-<p>
-    After adding a filter, you won't be able to set configuration directives.
-    Structure your code accordingly.
-</p>
-
-<!-- XXX: link to new documentation system -->
-
-<h2>Post-filter</h2>
-
-<p>
-    Remember our TransformImageScheme filter? That filter acted before we had
-    performed scheme validation; otherwise, the URI would have been filtered
-    out when it was discovered that there was no image scheme. Well, a post-filter
-    is run after scheme specific validation, so it's ideal for bulk
-    post-processing of URIs, including munging. To specify a URI as a post-filter,
-    set the <code>$post</code> member variable to TRUE.
-</p>
-
-<pre>class HTMLPurifier_URIFilter_MyPostFilter extends HTMLPurifier_URIFilter
-{
-    public $name = 'MyPostFilter';
-    public $post = true;
-    // ... extra code here
-}
-</pre>
-

-
-<p>Clients like their YouTube videos. It gives them a warm fuzzy feeling when
-they see a neat little embedded video player on their websites that can play
-the latest clips from their documentary &quot;Fido and the Bones of Spring&quot;.
-All joking aside, the ability to embed YouTube videos or other active
-content in their pages is something that a lot of people like.</p>
-
-<p>This is a <em>bad</em> idea. The moment you embed anything untrusted,
-you will definitely be slammed by a manner of nasties that can be
-embedded in things from your run of the mill Flash movie to
-<a href="http://blog.spywareguide.com/2006/12/myspace_phish_attack_leads_use.html">Quicktime movies</a>.
-Even <code>img</code> tags, which HTML Purifier allows by default, can be
-dangerous. Be distrustful of anything that tells a browser to load content
-from another website automatically.</p>
-
-<p>Luckily for us, however, whitelisting saves the day. Sure, letting users
-include any old random flash file could be dangerous, but if it's
-from a specific website, it probably is okay. If no amount of pleading will
-convince the people upstairs that they should just settle with just linking
-to their movies, you may find this technique very useful.</p>
-
-<h2>Looking in</h2>
-
-<p>Below is custom code that allows users to embed
-YouTube videos. This is not favoritism: this trick can easily be adapted for
-other forms of embeddable content.</p>
-
-<p>Usually, websites like YouTube give us boilerplate code that you can insert
-into your documents. YouTube's code goes like this:</p>
-
-<pre>
-&lt;object width=&quot;425&quot; height=&quot;350&quot;&gt;
-  &lt;param name=&quot;movie&quot; value=&quot;http://www.youtube.com/v/AyPzM5WK8ys&quot; /&gt;
-  &lt;param name=&quot;wmode&quot; value=&quot;transparent&quot; /&gt;
-  &lt;embed src=&quot;http://www.youtube.com/v/AyPzM5WK8ys&quot;
-         type=&quot;application/x-shockwave-flash&quot;
-         wmode=&quot;transparent&quot; width=&quot;425&quot; height=&quot;350&quot; /&gt;
-&lt;/object&gt;
-</pre>
-
-<p>There are two things to note about this code:</p>
-
-<ol>
-    <li><code>&lt;embed&gt;</code> is not recognized by W3C, so if you want
-        standards-compliant code, you'll have to get rid of it.</li>
-    <li>The code is exactly the same for all instances, except for the
-        identifier <tt>AyPzM5WK8ys</tt> which tells us which movie file
-        to retrieve.</li>
-</ol>
-
-<p>What point 2 means is that if we have code like <code>&lt;span
-class=&quot;youtube-embed&quot;&gt;AyPzM5WK8ys&lt;/span&gt;</code> your
-application can reconstruct the full object from this small snippet that
-passes through HTML Purifier <em>unharmed</em>.
-<a href="http://repo.or.cz/w/htmlpurifier.git?a=blob;hb=HEAD;f=library/HTMLPurifier/Filter/YouTube.php">Show me the code!</a></p>
-
-<p>And the corresponding usage:</p>
-
-<pre>&lt;?php
-    $config-&gt;set('Filter.YouTube', true);
-?&gt;</pre>
-
-<p>There is a bit going in the two code snippets, so let's explain.</p>
-
-<ol>
-    <li>This is a Filter object, which intercepts the HTML that is
-        coming into and out of the purifier. You can add as many
-        filter objects as you like. <code>preFilter()</code>
-        processes the code before it gets purified, and <code>postFilter()</code>
-        processes the code afterwards. So, we'll use <code>preFilter()</code> to
-        replace the object tag with a <code>span</code>, and <code>postFilter()</code>
-        to restore it.</li>
-    <li>The first preg_replace call replaces any YouTube code users may have
-        embedded into the benign span tag. Span is used because it is inline,
-        and objects are inline too. We are very careful to be extremely
-        restrictive on what goes inside the span tag, as if an errant code
-        gets in there it could get messy.</li>
-    <li>The HTML is then purified as usual.</li>
-    <li>Then, another preg_replace replaces the span tag with a fully fledged
-        object. Note that the embed is removed, and, in its place, a data
-        attribute was added to the object. This makes the tag standards
-        compliant! It also breaks Internet Explorer, so we add in a bit of
-        conditional comments with the old embed code to make it work again.
-        It's all quite convoluted but works.</li>
-</ol>
-
-<h2>Warning</h2>
-
-<p>There are a number of possible problems with the code above, depending
-on how you look at it.</p>
-
-<h3>Cannot change width and height</h3>
-
-<p>The width and height of the final YouTube movie cannot be adjusted. This
-is because I am lazy. If you really insist on letting users change the size
-of the movie, what you need to do is package up the attributes inside the
-span tag (along with the movie ID). It gets complicated though: a malicious
-user can specify an outrageously large height and width and attempt to crash
-the user's operating system/browser. You need to either cap it by limiting
-the amount of digits allowed in the regex or using a callback to check the
-number.</p>
-
-<h3>Trusts media's host's security</h3>
-
-<p>By allowing this code onto our website, we are trusting that YouTube has
-tech-savvy enough people not to allow their users to inject malicious
-code into the Flash files.  An exploit on YouTube means an exploit on your
-site.  Even though YouTube is run by the reputable Google, it
-<a href="http://ha.ckers.org/blog/20061213/google-xss-vuln/">doesn't</a>
-mean they are
-<a href="http://ha.ckers.org/blog/20061208/xss-in-googles-orkut/">invulnerable.</a>
-You're putting a certain measure of the job on an external provider (just as
-you have by entrusting your user input to HTML Purifier), and
-it is important that you are cognizant of the risk.</p>
-
-<h3>Poorly written adaptations compromise security</h3>
-
-<p>This should go without saying, but if you're going to adapt this code
-for Google Video or the like, make sure you do it <em>right</em>. It's
-extremely easy to allow a character too many in <code>postFilter()</code> and
-suddenly you're introducing XSS into HTML Purifier's XSS free output. HTML
-Purifier may be well written, but it cannot guard against vulnerabilities
-introduced after it has finished.</p>
-
-<h2>Help out!</h2>
-
-<p>If you write a filter for your favorite video destination (or anything
-like that, for that matter), send it over and it might get included
-with the core!</p>

-Extracting inline CSS from HTML Purifier
-    voodoofied: Assigning semantics to elements
-
-Sander Tekelenburg brought to my attention the poor programming style of
-inline CSS in HTML documents.  In an ideal world, we wouldn't be using inline
-CSS at all: everything would be assigned using semantic class attributes
-from an external stylesheet.
-
-With ExtractStyleBlocks and CSSTidy, this is now possible (when allowed, users
-can specify a style element which gets extracted from the user-submitted HTML, which
-the application can place in the head of the HTML document).  But there still
-is the issue of inline CSS that refuses to go away.
-
-The basic idea behind this feature is assign every element a unique identifier,
-and then move all of the CSS data to a style-sheet. This HTML:
-
-<div style="text-align:center">Big <span style="color:red;">things</span>!</div>
-
-into
-
-<div id="hp-12345">Big <span id="hp-12346">things</span>!</div>
-
-and a stylesheet that is:
-
-#hp-12345 {text-align:center;}
-#hp-12346 {color:red;}
-
-Beyond that, HTML Purifier can magically merge common CSS values together,
-and a whole manner of other heuristic things.  HTML Purifier should also
-make it easy for an admin to re-style the HTML semantically. Speed is not
-an issue. Also, better WYSIWYG editors are needed.

docs/proposal-errors.txt

@@ -1,211 +0,0 @@
-Considerations for ErrorCollection
-
-Presently, HTML Purifier takes a code-execution centric approach to handling
-errors. Errors are organized and grouped according to which segment of the
-code triggers them, not necessarily the portion of the input document that
-triggered the error. This means that errors are pseudo-sorted by category,
-rather than location in the document.
-
-One easy way to "fix" this problem would be to re-sort according to line number.
-However, the "category" style information we derive from naively following
-program execution is still useful. After all, each of the strategies which
-can report errors still process the document mostly linearly. Furthermore,
-not only do they process linearly, but the way they pass off operations to
-sub-systems mirrors that of the document. For example, AttrValidator will
-linearly proceed through elements, and on each element will use AttrDef to
-validate those contents. From there, the attribute might have more
-sub-components, which have execution passed off accordingly.
-
-In fact, each strategy handles a very specific class of "error."
-
-RemoveForeignElements   - element tokens
-MakeWellFormed          - element token ordering
-FixNesting              - element token ordering
-ValidateAttributes      - attributes of elements
-
-The crucial point is that while we care about the hierarchy governing these
-different errors, we *don't* care about any other information about what actually
-happens to the elements. This brings up another point: if HTML Purifier fixes
-something, this is not really a notice/warning/error; it's really a suggestion
-of a way to fix the aforementioned defects.
-
-In short, the refactoring to take this into account kinda sucks.
-
-Errors should not be recorded in order that they are reported. Instead, they
-should be bound to the line (and preferably element) in which they were found.
-This means we need some way to uniquely identify every element in the document,
-which doesn't presently exist. An easy way of adding this would be to track
-line columns. An important ramification of this is that we *must* use the
-DirectLex implementation.
-
-    1. Implement column numbers for DirectLex [DONE!]
-    2. Disable error collection when not using DirectLex [DONE!]
-
-Next, we need to re-orient all of the error declarations to place CurrentToken
-at utmost important. Since this is passed via Context, it's not always clear
-if that's available. ErrorCollector should complain HARD if it isn't available.
-There are some locations when we don't have a token available. These include:
-
-    * Lexing - this can actually have a row and column, but NOT correspond to
-      a token
-    * End of document errors - bump this to the end
-
-Actually, we *don't* have to complain if CurrentToken isn't available; we just
-set it as a document-wide error. And actually, nothing needs to be done here.
-
-Something interesting to consider is whether or not we care about the locations
-of attributes and CSS properties, i.e. the sub-objects that compose these things.
-In terms of consistency, at the very least attributes should have column/line
-numbers attached to them. However, this may be overkill, as attributes are
-uniquely identifiable. You could go even further, with CSS, but they are also
-uniquely identifiable.
-
-Bottom-line is, however, this information must be available, in form of the
-CurrentAttribute and CurrentCssProperty (theoretical) context variables, and
-it must be used to organize the errors that the sub-processes may throw.
-There is also a hierarchy of sorts that may make merging this into one context
-variable more sense, if it hadn't been for HTML's reasonably rigid structure.
-A CSS property will never contain an HTML attribute. So we won't ever get
-recursive relations, and having multiple depths won't ever make sense. Leave
-this be.
-
-We already have this information, and consequently, using start and end is
-*unnecessary*, so long as the context variables are set appropriately. We don't
-care if an error was thrown by an attribute transform or an attribute definition;
-to the end user these are the same (for a developer, they are different, but
-they're better off with a stack trace (which we should add support for) in such
-cases).
-
-    3. Remove start()/end() code. Don't get rid of recursion, though [DONE]
-    4. Setup ErrorCollector to use context information to setup hierarchies.
-       This may require a different internal format. Use objects if it gets
-       complex. [DONE]
-
-       ASIDE
-            More on this topic: since we are now binding errors to lines
-            and columns, a particular error can have three relationships to that
-            specific location:
-
-            1. The token at that location directly
-                RemoveForeignElements
-                AttrValidator (transforms)
-                MakeWellFormed
-            2. A "component" of that token (i.e. attribute)
-                AttrValidator (removals)
-            3. A modification to that node (i.e. contents from start to end
-               token) as a whole
-                FixNesting
-
-            This needs to be marked accordingly. In the presentation, it might
-            make sense keep (3) separate, have (2) a sublist of (1). (1) can
-            be a closing tag, in which case (3) makes no sense at all, OR it
-            should be related with its opening tag (this may not necessarily
-            be possible before MakeWellFormed is run).
-
-            So, the line and column counts as our identifier, so:
-
-            $errors[$line][$col] = ...
-
-            Then, we need to identify case 1, 2 or 3. They are identified as
-            such:
-
-            1. Need some sort of semaphore in RemoveForeignElements, etc.
-            2. If CurrentAttr/CurrentCssProperty is non-null
-            3. Default (FixNesting, MakeWellFormed)
-
-            One consideration about (1) is that it usually is actually a
-            (3) modification, but we have no way of knowing about that because
-            of various optimizations. However, they can probably be treated
-            the same. The other difficulty is that (3) is never a line and
-            column; rather, it is a range (i.e. a duple) and telling the user
-            the very start of the range may confuse them. For example,
-
-            <b>Foo<div>bar</div></b>
-            ^     ^
-
-            The node being operated on is <b>, so the error would be assigned
-            to the first caret, with a "node reorganized" error. Then, the
-            ChildDef would have submitted its own suggestions and errors with
-            regard to what's going in the internals.  So I suppose this is
-            ok. :-)
-
-            Now, the structure of the earlier mentioned ... would be something
-            like this:
-
-            object {
-                type = (token|attr|property),
-                value, // appropriate for type
-                errors => array(),
-                sub-errors = [recursive],
-            }
-
-            This helps us keep things agnostic. It is also sufficiently complex
-            enough to warrant an object.
-
-So, more wanking about the object format is in order. The way HTML Purifier is
-currently setup, the only possible hierarchy is:
-
-    token -> attr -> css property
-
-These relations do not exist all of the time; a comment or end token would not
-ever have any attributes, and non-style attributes would never have CSS properties
-associated with them.
-
-I believe that it is worth supporting multiple paths. At some point, we might
-have a hierarchy like:
-
-    * -> syntax
-      -> token -> attr -> css property
-                       -> url
-               -> css stylesheet <style>
-
-et cetera. Now, one of the practical implications of this is that every "node"
-on our tree is well-defined, so in theory it should be possible to either 1.
-create a separate class for each error struct, or 2. embed this information
-directly into HTML Purifier's token stream.  Embedding the information in the
-token stream is not a terribly good idea, since tokens can be removed, etc.
-So that leaves us with 1... and if we use a generic interface we can cut down
-on a lot of code we might need. So let's leave it like this.
-
-~~~~
-
-Then we setup suggestions.
-
-    5. Setup a separate error class which tells the user any modifications
-       HTML Purifier made.
-
-Some information about this:
-
-Our current paradigm is to tell the user what HTML Purifier did to the HTML.
-This is the most natural mode of operation, since that's what HTML Purifier
-is all about; it was not meant to be a validator.
-
-However, most other people have experience dealing with a validator. In cases
-where HTML Purifier unambiguously does the right thing, simply giving the user
-the correct version isn't a bad idea, but problems arise when:
-
-- The user has such bad HTML we do something odd, when we should have just
-  flagged the HTML as an error. Such examples are when we do things like
-  remove text from directly inside a <table> tag. It was probably meant to
-  be in a <td> tag or be outside the table, but we're not smart enough to
-  realize this so we just remove it. In such a case, we should tell the user
-  that there was foreign data in the table, but then we shouldn't "demand"
-  the user remove the data; it's more of a "here's a possible way of
-  rectifying the problem"
-
-- Giving line context for input is hard enough, but feasible; giving output
-  line context will be extremely difficult due to shifting lines; we'd probably
-  have to track what the tokens are and then find the appropriate out context
-  and it's not guaranteed to work etc etc etc.
-
-````````````
-
-Don't forget to spruce up output.
-
-    6. Output needs to automatically give line and column numbers, basically
-       "at line" on steroids. Look at W3C's output; it's ok. [PARTIALLY DONE]

 Filter Levels
     When one size *does not* fit all
 
-It makes little sense to constrain users to one set of HTML elements and

-and attributes they want.  This is fine: because HTML Purifier keeps close

+The object is constructed from two sources: subclassed versions of itself
+(classes) and Message files (messages).
+
+== General use ==
+
+You load a language object by calling the Language::factory() function. 
+This function the class file for the object (taking in account fallback 
+languages by using the fallback langauge's object but overloading the 
+language key) and returns that object. Nothing else happens.
+
+When a message/etc is requested, a lazy load initializor is called.  Now the
+real work starts.  We're first going to take the scenario that the language
+is not cached.  The system loads the Messages file by:
+
+    require( $filename );
+    $cache = compact( self::$mLocalisationKeys );	
+
+...where self::$mLocalisationKeys is the name of variables that could be used
+in the localization file. This lets you use things like:
+
+    $fallback = false;
+    $rtl = false;
+
+...and easily siphon them into arrays.
+
+Then, we load the $fallback language (if not set, English) to fill in the gaps in
+the messages.  There is specialized behavior for certain keys, as they can be
+mergeable maps, lists or alias lists (not sure what the last one is).

-THE UNIVERSAL DESIGN PATTERN: PROPERTIES
-Steve Yegge
-
-Implementation:
-    get(name)
-    put(name, value)
-    has(name)
-    remove(name)
-    iteration, with filtering [this will be our namespaces]
-    parent
-
-Representations:
-    - Keys are strings
-    - It's nice to not need to quote keys (if we formulate our own language,
-      consider this)
-    - Property not present representation (key missing)
-    - Frequent removal/re-add may have null help. If null is valid, use
-      another value. (PHP semantics are weird here)
-
-Data structures:
-    - LinkedHashMap is wonderful (O(1) access and maintains order)
-    - Using a special property that points to the parent is usual
-    - Multiple inheritance possible, need rules for which to lookup first
-    - Iterative inheritance is best
-    - Consider performance!
-
-Deletion
-    - Tricky problem with inheritance
-    - Distinguish between "not found" and "look in my parent for the property"
-    [Maybe HTML Purifier won't allow deletion]
-
-Read/write asymmetry (it's correct!)
-
-Read-only plists
-    - Allow ability to freeze [this is what we have already]
-    - Don't overuse it
-
-Performance:
-    - Intern strings (PHP does this already)
-    - Don't be case-insensitive
-    - If all properties in a plist are known a-priori, you can use a "perfect"
-      hash function. Often overkill.
-    - Copy-on-read caching "plundering" reduces lookup, but uses memory and can
-      grow stale. Use as last resort.
-    - Refactoring to fields. Watch for API compatibility, system complexity,
-      and lack of flexibility.
-    - Refrigerator: external data-structure to hold plists
-
-Transient properties:
-    [Don't need to worry about this]
-    - Use a separate plist for transient properties
-    - Non-numeric override; numeric should ADD
-    - Deletion: removeTransientProperty() and transientlyRemoveProperty()
-
-Persistence:
-    - XML/JSON are good
-    - Text-based is good for readability, maintainability and bootstrapping
-    - Compressed binary format for network transport [not necessary]
-    - RDBMS or XML database
-
-Querying: [not relevant]
-    - XML database is nice for XPath/XQuery
-    - jQuery for JSON
-    - Just load it all into a program
-
-Backfills/Data integrity:
-    - Use usual methods
-    - Lazy backfill is a nice hack
-
-Type systems:
-    - Flags: ReadOnly, Permanent, DontEnum
-    - Typed properties isn't that useful [It's also Not-PHP]
-    - Seperate meta-list of directive properties IS useful
-    - Duck typing is useful for systems designed fully around properties pattern

-HTML Purifier
-
-We are not happy with our current system of defining configuration directives,
-because it has become clear that things will get a lot nicer if we allow
-multiple namespaces, and there are some features that naturally lend themselves
-to inheritance, which we do not really support well.
-
-One of the considered implementation changes would be to go from a structure
-like:
-
-array(
-    'Namespace' => array(
-        'Directive' => 'val1',
-        'Directive2' => 'val2',
-    )
-)
-
-to:
-
-array(
-    'Namespace.Directive' => 'val1',
-    'Namespace.Directive2' => 'val2',
-)
-
-The below implementation takes more memory, however, and it makes it a bit
-complicated to grab all values from a namespace.
-
-The alternate implementation choice is to allow nested plists. This keeps
-iteration easy, but is problematic for inheritance (it would be difficult
-to distinguish a plist from an array) and retrieval (when specifying multiple
-namespaces we would need some multiple de-referencing).
-
-----
-
-We can bite the performance hit, and just do iteration with filter
-(the strncmp call should be relatively cheap). Then, users should be able
-to optimize doing something like:
-
-$config = HTMLPurifier_Config::createDefault();
-if (!file_exists('config.php')) {
-    // set up $config
-    $config->save('config.php');
-} else {
-    $config->load('config.php');
-}
-
-Or maybe memcache, or something. This means that "// set up $config" must
-not have any dynamic parts, or the user has to invalidate the cache when
-they do update it. We have to think about this a little more carefully; the
-file call might be more expensive.
-
-----
-
-This might get expensive, however, when we actually care about iterating
-over the configuration and want the actual values. So what about nesting the
-lists?
-
-"ns.sub.directive" => values['ns']['sub']['directive']
-
-We can distinguish between plists and arrays by using ArrayObjects for the
-plists, and regular arrays for the arrays? Alternatively, use ArrayObjects
-for the arrays, and regular arrays for the plists.
-
-----
-
-Implementation demands, and what has caused them:
-
-1. DefinitionCache, the HTML, CSS and URI namespaces have caches attached to them
-   Results:
-    - getBatchSerial()
-        - getBatch() : in general, the ability to traverse just a namespace
-
-2. AutoFormat/Filter, this is a plugin architecture, directives not hard-coded
-    - getBatch()
-
-3. Configuration form
-    - Namespaces used to organize directives
-
-Other than that, we have a pure plist. PERHAPS we should maintain separate things
-for these different demands.
-
-Issue 2: Directives for configuring the plugins are regular plists, but
-when enabling them, while it's "plist-ish", what you're really doing is adding
-them to an array of "autoformatters"/"filters" to enable. We can setup
-magic BC as well as in the new interface, but there should also be an
-add('AutoFormat', 'AutoParagraph'); which does the right thing.
-
-One thing to consider is whether or not inheritance rules will apply to these.
-I'd say yes. That means that they're still plisty, in fact, the underlying
-implementation will probably be a plist. However, they will get their OWN
-plists, and will NOT support nesting.
-
-Issue 1: Our current implementation is generally not efficient; md5(serialize($foo))
-is pretty expensive. So, I don't think there will be any problems if it
-gets "less" efficient, as long as we give users a properly fast alternative;
-DefinitionRev gives us a way to do this, by simply telling the user they must
-update it whenever they update Configuration directives as well. (There are
-obvious BC concerns here).
-
-In such a case, we simply iterate over our plist (performing full retrievals
-for each value), grab the entries we care about, and then serialize and hash.
-It's going to be slow either way, due to the ability of plists to inherit.
-If we ksort(), we don't have to traverse the entire array, however, the
-cost of a ksort() call may not be worth it.
-
-At this point, last time, I started worrying about the performance implications
-of allowing inheritance, and wondering whether or not I wanted to squash
-the plist. At first blush, our code might be under the assumption that
-accessing properties is cheap; but actually we prefer to copy out the value
-into a member variable if it's going to be used many times. With this is mind
-I don't think CPU consumption from a few nested function calls is going to
-be a problem. We *are* going to enforce a function only interface.
-
-The next issue at hand is how we're going to manage the "special" plists,
-which should still be able to be inherited. Basically, it means that multiple
-plists would be attached to the configuration object, which is not the
-best for memory performance. The alternative is to keep them all in one
-big plist, and then eat the one-time cost of traversing the entire plist
-to grab the appropriate values.
-
-I think at this point we can write the generic interface, and then set up separate
-plists if that ends up being necessary for performance (it probably won't.) Now
-lets code our generic plist implementation.
-
-----
-
-Iterating over the plist presents some problems. The way we've chosen to solve
-this is to squash all of the parents.
-
-----
-
-But I don't need iteration.

-Handling Content Model Changes
-
-
-1. Context
-
-The distinction between Transitional and Strict document types is somewhat
-of an anomaly in the lineage of XHTML document types (following 1.0, no
-doctypes do not have flavors: instead, modularization is used to let
-document authors vary their elements).  This transition is usually quite
-straight-forward, as W3C usually deprecates attributes or elements, which
-are quite easily handled using tag and attribute transforms.
-
-However, for two elements, <blockquote>, <body> and <address>, W3C elected
-to also change the content model.  <blockquote> and <body> originally
-accepted both inline and block elements, but in the strict doctype they
-only allow block elements.  With <address>, the situation is inverted:
-<p> tags were now forbidden from appearing within this tag.
-
-
-2. Current situation
-
-Currently, HTML Purifier treats <blockquote> specially during Tidy mode
-using a custom ChildDef class StrictBlockquote.  StrictBlockquote
-operates similarly to Required, except that when it encounters an inline
-element, it will wrap it in a block tag (as specified by
-%HTML.BlockWrapper, the default is <p>).  The naming suggests it can
-only be used for <blockquote>s, although it may be possible to
-genericize it to work on other cases of this nature (this would be of
-little practical application, as no other element in XHTML 1.1 or earlier
-has a block-only content model).
-
-Tidy currently contains no custom, lenient implementation for <address>.
-If one were to be written, it would likely operate on the principle that,
-when a <p> tag were to be encountered, it would be replaced with a
-leading and trailing <br /> tag (the contents of <p>, being inline, are
-not an issue).  There is no prior work with this sort of operation.
-
-
-3. Outside applicability
-
-There are a number of other elements that contain restrictive content
-models, such as <ul> or <span> (the latter is restrictive in that it
-does not allow block elements).  In the former case, an errant node
-is eliminated completely, in the latter case, the text of the node
-would is preserved (as the parent node does allow PCDATA).  Custom
-content model implementations probably are not the best way of handling
-these cases, instead, node bubbling should be implemented instead.

-The Modularization of HTMLDefinition in HTML Purifier
-
-WARNING: This document was drafted before the implementation of this
-    system, and some implementation details may have evolved over time.
-
-HTML Purifier uses the modularization of XHTML
-<http://www.w3.org/TR/xhtml-modularization/> to organize the internals
-of HTMLDefinition into a more manageable and extensible fashion. Rather
-than have one super-object, HTMLDefinition is split into HTMLModules,
-each of which are responsible for defining elements, their attributes,
-and other properties (for a more indepth coverage, see
-/library/HTMLPurifier/HTMLModule.php's docblock comments). These modules
-are managed by HTMLModuleManager.
-
-Modules that we don't support but could support are:
-
-    * 5.6. Table Modules
-          o 5.6.1. Basic Tables Module [?]
-    * 5.8. Client-side Image Map Module [?]
-    * 5.9. Server-side Image Map Module [?]
-    * 5.12. Target Module [?]
-    * 5.21. Name Identification Module [deprecated]
-
-These modules would be implemented as "unsafe":
-
-    * 5.2. Core Modules
-          o 5.2.1. Structure Module
-    * 5.3. Applet Module
-    * 5.5. Forms Modules
-          o 5.5.1. Basic Forms Module
-          o 5.5.2. Forms Module
-    * 5.10. Object Module
-    * 5.11. Frames Module
-    * 5.13. Iframe Module
-    * 5.14. Intrinsic Events Module
-    * 5.15. Metainformation Module
-    * 5.16. Scripting Module
-    * 5.17. Style Sheet Module
-    * 5.19. Link Module
-    * 5.20. Base Module
-
-We will not be using W3C's XML Schemas or DTDs directly due to the lack
-of robust tools for handling them (the main problem is that all the
-current parsers are usually PHP 5 only and solely-validating, not
-correcting).
-
-This system may be generalized and ported over for CSS.
-
-== General Use-Case ==
-
-The outwards API of HTMLDefinition has been largely preserved, not
-only for backwards-compatibility but also by design. Instead,
-HTMLDefinition can be retrieved "raw", in which it loads a structure
-that closely resembles the modules of XHTML 1.1. This structure is very
-dynamic, making it easy to make cascading changes to global content
-sets or remove elements in bulk.
-
-However, once HTML Purifier needs the actual definition, it retrieves
-a finalized version of HTMLDefinition. The finalized definition involves
-processing the modules into a form that it is optimized for multiple
-calls. This final version is immutable and, even if editable, would
-be extremely hard to change.
-
-So, some code taking advantage of the XHTML modularization may look
-like this:
-
-<?php
-    $config = HTMLPurifier_Config::createDefault();
-    $def =& $config->getHTMLDefinition(true); // reference to raw
-    $def->addElement('marquee', 'Block', 'Flow', 'Common');
-    $purifier = new HTMLPurifier($config);
-    $purifier->purify($html); // now the definition is finalized
-?>
-
-== Inclusions ==
-
-One of the nice features of HTMLDefinition is that piggy-backing off
-of global attribute and content sets is extremely easy to do.
-
-=== Attributes ===
-
-HTMLModule->elements[$element]->attr stores attribute information for the
-specific attributes of $element. This is quite close to the final
-API that HTML Purifier interfaces with, but there's an important
-extra feature: attr may also contain a array with a member index zero.
-
-<?php
-    HTMLModule->elements[$element]->attr[0] = array('AttrSet');
-?>
-
-Rather than map the attribute key 0 to an array (which should be
-an AttrDef), it defines a number of attribute collections that should
-be merged into this elements attribute array.
-
-Furthermore, the value of an attribute key, attribute value pair need
-not be a fully fledged AttrDef object. They can also be a string, which
-signifies a AttrDef that is looked up from a centralized registry
-AttrTypes. This allows more concise attribute definitions that look
-more like W3C's declarations, as well as offering a centralized point
-for modifying the behavior of one attribute type. And, of course, the
-old method of manually instantiating an AttrDef still works.
-
-=== Attribute Collections ===
-
-Attribute collections are stored and processed in the AttrCollections
-object, which is responsible for performing the inclusions signified
-by the 0 index. These attribute collections, too, are mutable, by
-using HTMLModule->attr_collections. You may add new attributes
-to a collection or define an entirely new collection for your module's
-use. Inclusions can also be cumulative.
-
-Attribute collections allow us to get rid of so called "global attributes"
-(which actually aren't so global).
-
-=== Content Models and ChildDef ===
-
-An implementation of the above-mentioned attributes and attribute
-collections was applied to the ChildDef system. HTML Purifier uses
-a proprietary system called ChildDef for performance and flexibility
-reasons, but this does not line up very well with W3C's notion of
-regexps for defining the allowed children of an element.
-
-HTMLPurifier->elements[$element]->content_model and
-HTMLPurifier->elements[$element]->content_model_type store information
-about the final ChildDef that will be stored in
-HTMLPurifier->elements[$element]->child (we use a different variable
-because the two forms are sufficiently different).
-
-$content_model is an abstract, string representation of the internal
-state of ChildDef, while $content_model_type is a string identifier
-of which ChildDef subclass to instantiate. $content_model is processed
-by substituting all content set identifiers (capitalized element names)
-with their contents. It is then parsed and passed into the appropriate
-ChildDef class, as defined by the ContentSets->getChildDef() or the
-custom fallback HTMLModule->getChildDef() for custom child definitions
-not in the core.
-
-You'll need to use these facilities if you plan on referencing a content
-set like "Inline" or "Block", and using them is recommended even if you're
-not due to their conciseness.
-
-A few notes on $content_model: it's structure can be as complicated
-as you want, but the pipe symbol (|) is reserved for defining possible
-choices, due to the content sets implementation. For example, a content
-model that looks like:
-
-"Inline -> Block -> a"
-
-...when the Inline content set is defined as "span | b" and the Block
-content set is defined as "div | blockquote", will expand into:
-
-"span | b -> div | blockquote -> a"
-
-The custom HTMLModule->getChildDef() function will need to be able to
-then feed this information to ChildDef in a usable manner.
-
-=== Content Sets ===
-
-Content sets can be altered using HTMLModule->content_sets, an associative
-array of content set names to content set contents. If the content set
-already exists, your values are appended on to it (great for, say,
-registering the font tag as an inline element), otherwise it is
-created. They are substituted into content_model.

+Is HTML Purifier Strict or Transitional?
+    A little bit of helpful guidance
+
+Despite the fact that HTML Purifier professes only to support transitional
+HTML, it rejects a lot of attributes and elements that are actually, indeed,
+valid. You can investigate progress.html to find out precisely what we
+are doing to these *deprecated* attributes.
+
+However, users have found that Strict HTML imposes some quite unreasonable
+restrictions on certain things. The start and value attributes in ol and
+li (respectively) perhaps are the most contested. There's is currently no
+widely supported browser method short of JavaScript that can replace these
+two deprecated elements. HTML Purifier does not currently support them, but
+it might behoove us to do so while our output is still transitional.
+
+Fortunantely, that's the only real bugger case. The others have near-perfect
+CSS equivalents, and were presentational anyway. However, the other question
+pops up: should we always convert these to the CSS forms when 1. the spec
+allows them anyway and 2. older browsers support them better? After all, the
+whole point about CSS is to seperate styling from content, so inline styling
+doesn't solve that problem.
+
+It's an icky question, and we'll have to deal with it as more and more 
+transforms get implemented.  As of right now, however, we currently support
+these loose-only constructs in loose mode:
+
+- <ul start="1">, <li value="1"> attributes
+- <u>, <strike>, <s> tags
+- flow children in <blockquote>
+- mixed children in <address>
+
+The changed child definitions as well as the ul.start li.value are the most
+compelling reasons why loose should be used.  We may want offer disabling <u>,
+<strike> and <s> by themselves.

+I don't think we need to worry about them.  Untrusted users shouldn't be
+submitting applications, eh?  But if some interesting attribute pops up in
+their spec, and might be worth supporting, stick it here.
 
-URL: http://www.whatwg.org/specs/web-apps/current-work/
-
-HTML 5 defines a kaboodle of new elements and attributes, as well as
-some well-defined, "quirks mode" HTML parsing.  Although WHATWG professes
-to be targeted towards web applications, many of their semantic additions
-would be quite useful in regular documents. Eventually, HTML
-Purifier will need to audit their lists and figure out what changes need
-to be made.  This process is complicated by the fact that the WHATWG
-doesn't buy into W3C's modularization of XHTML 1.1: we may need
-to remodularize HTML 5 (probably done by section name). No sense in
-committing ourselves till the spec stabilizes, though.
-
-More immediately speaking though, however, is the well-defined parsing
-behavior that HTML 5 adds. While I have little interest in writing
-another DirectLex parser, other parsers like ph5p
-<http://jero.net/lab/ph5p/> can be adapted to DOMLex to support much more
-flexible HTML parsing (a cool feature I've seen is how they resolve
-<b>bold<i>both</b>italic</i>).

+Getting XHTML 1.1 Working
+
+It's quite simple, according to <http://www.w3.org/TR/xhtml11/changes.html>
+
+1. Scratch lang entirely in favor of xml:lang
+2. Scratch name entirely in favor of id (partially-done)
+3. Support Ruby <http://www.w3.org/TR/2001/REC-ruby-20010531/>
+
+...but that's only an informative section. More things to do:
+
+1. Scratch style attribute (it's deprecated)
+2. Be module-aware
+3. Cross-reference minimal content models with existing DTDs and determine
+   changes (todo)
+4. Watch out for the Legacy Module
+<http://www.w3.org/TR/2001/REC-xhtml-modularization-20010410/abstract_modules.html#s_legacymodule>
+5. Let users specify their own custom modules
+6. Study Modularization document

-HTML Purifier Extras
-    The Method Behind The Madness!
-
-The extras/ folder in HTML Purifier contains--you guessed it--extra things
-for HTML Purifier.  Specifically, these are two extra libraries called
-FSTools and ConfigSchema.  They're extra for a reason: you don't need them
-if you're using HTML Purifier for normal usage: filtering HTML.  However,
-if you're a developer, and would like to test HTML Purifier, or need to
-use one of HTML Purifier's maintenance scripts, chances are they'll need
-these libraries. Who knows: maybe you'll find them useful too!
-
-Here are the libraries:
-
-
-FSTools
--------
-
-Short for File System Tools, this is a poor-man's object-oriented wrapper for
-the filesystem. It currently consists of two classes:
-
-- FSTools: This is a singleton that contains a manner of useful functions
-  such as recursive glob, directory removal, etc, as well as the ability
-  to call arbitrary native PHP functions through it like $FS->fopen(...).
-  This makes it a lot simpler to mock these filesystem calls for unit testing.
-
-- FSTools_File: This object represents a single file, and has almost any
-  method imaginable one would need.
-
-Check the files themselves for more information.
