+--DESCRIPTION--
+If null, class will auto-detect the doctype and, if matching XHTML 1.1 or

+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

+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.

+<p>
+ If you would like users to be able to define external stylesheets, but

+ It accepts any valid CSS selector, and will prepend this to any
+ CSS declaration extracted from the document. For example, if this

+ selector <code>a:hover</code>, the final selector will be
+ <code>#user-content a:hover</code>.

+<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

+ Purifier, and I am working to get it fixed. Until then, HTML Purifier
+ performs a basic check to prevent this.

+URI.Munge
+TYPE: string/null
+VERSION: 1.3.0
+DEFAULT: NULL
+--DESCRIPTION--
+
+<p>
+ Munges all browsable (usually http, https and ftp)
+ absolute URIs into another URI, usually a URI redirection service.
+ This directive accepts a URI, formatted with a <code>%s</code> where
+ the url-encoded original URI should be inserted (sample:
+ <code>http://www.google.com/url?q=%s</code>).
+</p>
+<p>
+ Uses for this directive:
+</p>
+<ul>
+ <li>
+ Prevent PageRank leaks, while being fairly transparent
+ to users (you may also want to add some client side JavaScript to
+ override the text in the statusbar). <strong>Notice</strong>:
+ Many security experts believe that this form of protection does not deter spam-bots.
+ </li>
+ <li>
+ Redirect users to a splash page telling them they are leaving your
+ website. While this is poor usability practice, it is often mandated
+ in corporate environments.
+ </li>
+</ul>
+<p>
+ Prior to HTML Purifier 3.1.1, this directive also enabled the munging
+ of browsable external resources, which could break things if your redirection
+ script was a splash page or used <code>meta</code> tags. To revert to
+ previous behavior, please use %URI.MungeResources.
+</p>
+<p>
+ You may want to also use %URI.MungeSecretKey along with this directive
+ in order to enforce what URIs your redirector script allows. Open
+ redirector scripts can be a security risk and negatively affect the
+ reputation of your domain name.
+</p>
+<p>
+ Starting with HTML Purifier 3.1.1, there is also these substitutions:
+</p>
+<table>
+ <thead>
+ <tr>
+ <th>Key</th>
+ <th>Description</th>
+ <th>Example <code>&lt;a href=""&gt;</code></th>
+ </tr>
+ </thead>
+ <tbody>
+ <tr>
+ <td>%r</td>
+ <td>1 - The URI embeds a resource<br />(blank) - The URI is merely a link</td>
+ <td></td>
+ </tr>
+ <tr>
+ <td>%n</td>
+ <td>The name of the tag this URI came from</td>

+ </tr>
+ <tr>
+ <td>%p</td>
+ <td>The name of the CSS property this URI came from, or blank if irrelevant</td>
+ <td></td>
+ </tr>
+ </tbody>
+</table>
+<p>
+ Admittedly, these letters are somewhat arbitrary; the only stipulation
+ was that they couldn't be a through f. r is for resource (I would have preferred
+ e, but you take what you can get), n is for name, m
+ was picked because it came after n (and I couldn't use a), p is for
+ property.

+TYPE: string/null
+VERSION: 3.1.1
+DEFAULT: NULL
+--DESCRIPTION--
+<p>
+ This directive enables secure checksum generation along with %URI.Munge.
+ It should be set to a secure key that is not shared with anyone else.
+ The checksum can be placed in the URI using %t. Use of this checksum
+ affords an additional level of protection by allowing a redirector
+ to check if a URI has passed through HTML Purifier with this line:
+</p>
+
+<pre>$checksum === sha1($secret_key . ':' . $url)</pre>
+
+<p>
+ If the output is TRUE, the redirector script should accept the URI.
+</p>
+
+<p>
+ Please note that it would still be possible for an attacker to procure
+ secure hashes en-mass by abusing your website's Preview feature or the
+ like, but this service affords an additional level of protection
+ that should be combined with website blacklisting.
+</p>
+
+<p>
+ Remember this has no effect if %URI.Munge is not on.

+URI.OverrideAllowedSchemes
+TYPE: bool
+DEFAULT: true
+--DESCRIPTION--
+If this is set to true (which it is by default), you can override
+%URI.AllowedSchemes by simply registering a HTMLPurifier_URIScheme to the
+registry. If false, you will also have to update that directive in order
+to add more schemes.
