+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.

+--DESCRIPTION--
+<p>
+  If you would like users to be able to define external stylesheets, but
+  only allow them to specify CSS declarations for a specific node and
+  prevent them from fiddling with other elements, use this directive.
+  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.

+EXTERNAL: CSSTidy
+--DESCRIPTION--
+<p>
+  This directive turns on the style block extraction filter, which removes

+  and places them in the <code>StyleBlocks</code> context variable, for further
+  use by you, usually to be placed in an external stylesheet, or a

+  <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.

+TYPE: bool
+VERSION: 1.3.0

+--DESCRIPTION--
+Disables the embedding of external resources, preventing users from
+embedding things like images from other hosts. This prevents access
+tracking (good for email viewers), bandwidth leeching, cross-site request
+forging, goatse.cx posting, and other nasties, but also results in a loss
+of end-user functionality (they can't directly post a pic they posted from
+Flickr anymore). Use it if you don't have a robust user-content moderation
+team.

+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>
+            <td>a</td>
+        </tr>
+        <tr>
+            <td>%m</td>
+            <td>The name of the attribute this URI came from</td>
+            <td>href</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.

+URI.MungeSecretKey
+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 === hash_hmac("sha256", $url, $secret_key)</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.
