+Configuration Ideas
+
+Here are some theoretical configuration ideas that we could implement some
+time.
+
+%Attr.IDPrefix - prefix all ids with this
+%Attr.RewriteFragments - if there's %Attr.IDPrefix we may want to transparently
+    rewrite the URLs we parse too.  However, we can only do it when it's a pure
+    anchor link, so it's not foolproof
+
+// determines how the classes array should be construed:
+// blacklist - allow allow except those in $classes_blacklist
+// whitelist - only allow those in $classes_whitelist
+// when one is chosen, the other has no effect
+%Attr.ClassBlacklist 
+%Attr.ClassWhitelist 
+%Attr.ClassListMode 
+
+// designate whether or not to allow numerals in language code subtags
+// RFC 1766, the current standard referenced by XML, does not permit
+//           numbers, but,
+// RFC 3066, the superseding best practice standard since January 2001,
+//           permits them.
+// we allow numbers by default, although you generally never see them
+// at all.
+%Attr.LangAlphaOnly 
+
+// max amount of pixels allowed to be specified
+var $attr_pixels_hmax = 600;  // horizontal context
+var $attr_pixels_vmax = 1200; // vertical context
+
+// allowed URI schemes
+var $uri_schemes = array(
+    // based off of MediaWiki's default settings
+    // the ones that definitely must be implemented (they're the same though)
+    'http'  => true, // "Hypertext Transfer Protocol", nuf' said
+    'https' => true, // HTTP over SSL (Secure Socket Layer)
+    // quite useful, but not necessary
+    'mailto' => true,// Email
+    'ftp'   => true, // "File Transfer Protocol"
+    'irc'   => true, // "Internet Relay Chat", usually needs another app
+    // obscure
+    'telnet' => true,// network protocol for non-secure remote terminal sessions
+    // for Usenet, these two are similar, but distinct
+    'nntp'  => true, // individual Netnews articles
+    'news'  => true  // newsgroup or individual Netnews articles
+    // gopher and worldwind excluded
+);
+
+// will munge all URIs to a different URI, which should redirect
+// the user to the applicable page. A urlencoded version of the URI
+// will replace any instances of %s in the string. One possible
+// string is 'http://www.google.com/url?q=%s'. Useful for preventing
+// pagerank from being sent to other sites
+var $uri_munge = false;
+
+// will add rel="nofollow" to all links, also helps prevent pagerank
+// from going around
+var $uri_add_relnofollow = false;
+
+// web root of the website, we'll try to auto-detect it. Something
+// like 'www.example.com/'???
+var $uri_webroot = null;
+
+// transform all relative URIs into their absolute forms, requires
+// $uri_webroot
+var $uri_make_absolute = false;
+
+// disables external links, requires $uri_webroot
+var $uri_disable_external = false;
