Attr.ClassUseCDATA
TYPE: bool/null
DEFAULT: null
VERSION: 4.0.0
--DESCRIPTION--
If null, class will auto-detect the doctype and, if matching XHTML 1.1 or
XHTML 2.0, will use the restrictive NMTOKENS specification of class. Otherwise,
it will use a relaxed CDATA definition. If true, the relaxed CDATA definition
is forced; if false, the NMTOKENS definition is forced. To get behavior
of HTML Purifier prior to 4.0.0, set this directive to false.
Some rational behind the auto-detection:
in previous versions of HTML Purifier, it was assumed that the form of
class was NMTOKENS, as specified by the XHTML Modularization (representing
XHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, however
specify class as CDATA. HTML 5 effectively defines it as CDATA, but
with the additional constraint that each name should be unique (this is not
explicitly outlined in previous specifications).

<li>Applies to inline elements or text with double newlines in nodes

To prevent auto-paragraphing as a content-producer, refrain from using
double-newlines except to specify a new paragraph or in contexts where
it has special meaning (whitespace usually has no meaning except in
tags like <code>pre</code>, so this should not be difficult.) To prevent
the paragraphing of inline text adjacent to block elements, wrap them
in <code>div</code> tags (the behavior is slightly different outside of
the root node.)

AutoFormat.RemoveEmpty
TYPE: bool
VERSION: 3.2.0
DEFAULT: false
--DESCRIPTION--
<p>
When enabled, HTML Purifier will attempt to remove empty elements that
contribute no semantic information to the document. The following types
of nodes will be removed:
</p>
<ul><li>
Tags with no attributes and no content, and that are not empty
elements (remove <code>&lt;a&gt;&lt;/a&gt;</code> but not
<code>&lt;br /&gt;</code>), and
</li>
<li>
Tags with no content, except for:<ul>
<li>The <code>colgroup</code> element, or</li>
<li>
Elements with the <code>id</code> or <code>name</code> attribute,
when those attributes are permitted on those elements.
</li>
</ul></li>
</ul>
<p>
Please be very careful when using this functionality; while it may not
seem that empty elements contain useful information, they can alter the
layout of a document given appropriate styling. This directive is most
useful when you are processing machine-generated HTML, please avoid using
it on regular user HTML.
</p>
<p>
Elements that contain only whitespace will be treated as empty. Non-breaking
spaces, however, do not count as whitespace. See
%AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.
</p>
<p>
This algorithm is not perfect; you may still notice some empty tags,
particularly if a node had elements, but those elements were later removed
because they were not permitted in that context, or tags that, after
being auto-closed by another tag, where empty. This is for safety reasons
to prevent clever code from breaking validation. The general rule of thumb:
if a tag looked empty on the way in, it will get removed; if HTML Purifier
made it empty, it will stay.

but it can help work around a bug in libxml where embedded
HTML elements inside script sections cause the parser to
choke. To revert to pre-4.9.0 behavior, set this to false.
This directive has no effect if %Core.Trusted is true,
%Core.RemoveScriptContents is false, or %Core.HiddenElements
does not contain script.

Core.AllowHostnameUnderscore
TYPE: bool
VERSION: 4.6.0
DEFAULT: false
--DESCRIPTION--
<p>
By RFC 1123, underscores are not permitted in host names.
(This is in contrast to the specification for DNS, RFC
2181, which allows underscores.)
However, most browsers do the right thing when faced with
an underscore in the host name, and so some poorly written
websites are written with the expectation this should work.
Setting this parameter to true relaxes our allowed character
check so that underscores are permitted.

If for some reason you are unable to convert all webpages to UTF-8, you can

absolutely no characters outside of the selected character encoding will be
preserved, not even the ones that have been ampersand escaped (this is due
to a UTF-8 specific <em>feature</em> that automatically resolves all
entities), making it pretty useless for anything except the most I18N-blind
applications, although %Core.EscapeNonASCIICharacters offers fixes this
trouble with another tradeoff. This directive only accepts ISO-8859-1 if
iconv is not enabled.

TYPE: bool
VERSION: 1.4.0

This directive overcomes a deficiency in %Core.Encoding by blindly
converting all non-ASCII characters into decimal numeric entities before
converting it to its native encoding. This means that even characters that
can be expressed in the non-UTF-8 encoding will be entity-ized, which can
be a real downer for encodings like Big5. It also assumes that the ASCII
repetoire is available, although this is the case for almost all encodings.

Prior to HTML Purifier 4.9.0, entities were decoded by performing

not have a trailing semicolon, but only if there weren't any trailing
alphanumeric characters.

<tr><td>&amp;yen=</td><td>&yen;=</td><td>&yen;=</td></tr>
</table>
<p>
In HTML Purifier 4.9.0, we changed the behavior of entity parsing
to match entities that had missing trailing semicolons in less
cases, to more closely match HTML5 parsing behavior:
</p>
<table>
<tr><th>Original</th><th>Text</th><th>Attribute</th></tr>
<tr><td>&amp;yen;</td><td>&yen;</td><td>&yen;</td></tr>

It accepts any valid CSS selector, and will prepend this to any
CSS declaration extracted from the document. For example, if this
directive is set to <code>#user-content</code> and a user uses the
selector <code>a:hover</code>, the final selector will be
<code>#user-content a:hover</code>.
</p>
<p>
The comma shorthand may be used; consider the above example, with
<code>#user-content, #user-content2</code>, the final selector will
be <code>#user-content a:hover, #user-content2 a:hover</code>.
</p>
<p>
<strong>Warning:</strong> It is possible for users to bypass this measure
using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML
Purifier, and I am working to get it fixed. Until then, HTML Purifier
performs a basic check to prevent this.

<strong>Warning:</strong> It is possible for a user to mount an
imagecrash attack using this CSS. Counter-measures are difficult;
it is not simply enough to limit the range of CSS lengths (using
relative lengths with many nesting levels allows for large values
to be attained without actually specifying them in the stylesheet),
and the flexible nature of selectors makes it difficult to selectively
disable lengths on image tags (HTML Purifier, however, does disable
CSS width and height in inline styling). There are probably two effective
counter measures: an explicit width and height set to auto in all
images in your document (unlikely) or the disabling of width and
height (somewhat reasonable). Whether or not these measures should be
used is left to the reader.

HTML.Allowed
TYPE: itext/null
VERSION: 2.0.0
DEFAULT: NULL
--DESCRIPTION--
<p>
This is a preferred convenience directive that combines
%HTML.AllowedElements and %HTML.AllowedAttributes.
Specify elements and attributes that are allowed using:
<code>element1[attr1|attr2],element2...</code>. For example,
if you would like to only allow paragraphs and links, specify
<code>a[href],p</code>. You can specify attributes that apply
to all elements using an asterisk, e.g. <code>*[lang]</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.

HTML.AllowedAttributes
TYPE: lookup/null
VERSION: 1.3.0

If HTML Purifier's attribute set is unsatisfactory, overload it!
The syntax is "tag.attr" or "*.attr" for the global attributes
(style, id, class, dir, lang, xml:lang).
</p>
<p>
<strong>Warning:</strong> If another directive conflicts with the
elements here, <em>that</em> directive will win and override. For
example, %HTML.EnableAttrID will take precedence over *.id in this
directive. You must set that directive to true before you can use
IDs at all.

A regexp, which if it matches the body of a comment, indicates that
it should be allowed. Trailing and leading spaces are removed prior
to running this regular expression.
<strong>Warning:</strong> Make sure you specify
correct anchor metacharacters <code>^regex$</code>, otherwise you may accept
comments that you did not mean to! In particular, the regex <code>/foo|bar/</code>
is probably not sufficiently strict, since it also allows <code>foobar</code>.

<p>
A doctype comes with a set of usual modules to use. Without having
to mucking about with the doctypes, you can quickly activate or
disable these modules by specifying which modules you wish to allow
with this directive. This is most useful for unit testing specific
modules, although end users may find it useful for their own ends.
</p>

If you specify a module that does not exist, the manager will silently
fail to use it, so be careful! User-defined modules are not affected
by this directive. Modules defined in %HTML.CoreModules are not
affected by this directive.

HTML.DefinitionID
TYPE: string/null
DEFAULT: NULL
VERSION: 2.0.0
--DESCRIPTION--
<p>
Unique identifier for a custom-built HTML definition. If you edit
the raw version of the HTMLDefinition, introducing changes that the
configuration object does not reflect, you must specify this variable.
If you change your custom edits, you should change this directive, or
clear your cache. Example:
</p>
<pre>
$config = HTMLPurifier_Config::createDefault();
$config->set('HTML', 'DefinitionID', '1');
$def = $config->getHTMLDefinition();
$def->addAttribute('a', 'tabindex', 'Number');
</pre>
<p>
In the above example, the configuration is still at the defaults, but
using the advanced API, an extra attribute has been added. The
configuration object normally has no way of knowing that this change
has taken place, so it needs an extra directive: %HTML.DefinitionID.
If someone else attempts to use the default configuration, these two
pieces of code will not clobber each other in the cache, since one has
an extra directive attached to it.
</p>
<p>
You <em>must</em> specify a value to this directive to use the
advanced API features.

--DESCRIPTION--
<p>
While this directive is similar to %HTML.AllowedAttributes, for
forwards-compatibility with XML, this attribute has a different syntax. Instead of
<code>tag.attr</code>, use <code>tag@attr</code>. To disallow <code>href</code>
attributes in <code>a</code> tags, set this directive to
<code>a@href</code>. You can also disallow an attribute globally with
<code>attr</code> or <code>*@attr</code> (either syntax is fine; the latter
is provided for consistency with %HTML.AllowedAttributes).

<strong>Warning:</strong> This directive complements %HTML.ForbiddenElements,
accordingly, check
out that directive for a discussion of why you
should think twice before using this directive.

This was, perhaps, the most requested feature ever in HTML
Purifier. Please don't abuse it! This is the logical inverse of

If possible, %HTML.Allowed is recommended over this directive, because it
can sometimes be difficult to tell whether or not you've forbidden all of
the behavior you would like to disallow. If you forbid <code>img</code>
with the expectation of preventing images on your site, you'll be in for
a nasty surprise when people start using the <code>background-image</code>
CSS property.
