-HTML.Allowed
-TYPE: itext/null
-VERSION: 2.0.0
-DEFAULT: NULL
---DESCRIPTION--
-
-<p>
-    This is a convenience directive that rolls the functionality of
-    %HTML.AllowedElements and %HTML.AllowedAttributes into one directive.
-    Specify elements and attributes that are allowed using:
-    <code>element1[attr1|attr2],element2...</code>. You can also use
-    newlines instead of commas to separate elements.
-</p>
-<p>
-    <strong>Warning</strong>:
-    All of the constraints on the component directives are still enforced.
-    The syntax is a <em>subset</em> of TinyMCE's <code>valid_elements</code>
-    whitelist: directly copy-pasting it here will probably result in
-    broken whitelists. If %HTML.AllowedElements or %HTML.AllowedAttributes
-    are set, this directive has no effect.
