+ <notes>
+HTML Purifier 4.0 is a major feature release focused on configuration
+It deprecates the $config->set('Ns', 'Directive', $value) syntax for
+$config->set('Ns.Directive', $value); both syntaxes work but the
+former will throw errors. There are also some new features: robust
+support for name/id, configuration inheritance, remove nbsp in
+the RemoveEmpty autoformatter, userland configuration directives
+and configuration serialization.

+ <notes>
+HTML Purifier 4.0 is a major feature release focused on configuration
+It deprecates the $config->set('Ns', 'Directive', $value) syntax for
+$config->set('Ns.Directive', $value); both syntaxes work but the
+former will throw errors. There are also some new features: robust
+support for name/id, configuration inheritance, remove nbsp in
+the RemoveEmpty autoformatter, userland configuration directives
+and configuration serialization.

+ *
+ * HTML Purifier is an HTML filter that will take an arbitrary snippet of
+ * HTML and rigorously test, validate and filter it into a version that
+ * is safe for output onto webpages. It achieves this by:
+ *
+ * -# Lexing (parsing into tokens) the document,
+ * -# Executing various strategies on the tokens:
+ * -# Removing all elements not in the whitelist,
+ * -# Making the tokens well-formed,
+ * -# Fixing the nesting of the nodes, and
+ * -# Validating attributes of the nodes; and
+ * -# Generating HTML from the purified tokens.
+ *
+ * However, most users will only need to interface with the HTMLPurifier
+ * and HTMLPurifier_Config.

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

+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).

+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><a></a></code> but not
+ <code><br /></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.

+ 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.

+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><a href=""></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>

+ </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.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.

+ * does not actually define any implementation, but offers commonly used
+ * convenience functions for subclasses.

+ * Takes a well formed list of tokens and fixes their nesting.

+ * HTML elements dictate which elements are allowed to be their children,

+ * much more rigorous definitions: tables, for instance, require a specific
+ * order for their elements. There are also constraints not expressible by
+ * document type definitions, such as the chameleon nature of ins/del

+ *
+ * The first major objective of this strategy is to iterate through all the
+ * nodes (not tokens) of the list of tokens and determine whether or not
+ * their children conform to the element's definition. If they do not, the
+ * child definition may optionally supply an amended list of elements that
+ * is valid or require that the entire node be deleted (and the previous
+ * node rescanned).
+ *
+ * The second objective is to ensure that explicitly excluded elements of
+ * an element do not appear in its children. Code that accomplishes this
+ * task is pervasive through the strategy, though the two are distinct tasks
+ * and could, theoretically, be seperated (although it's not recommended).
+ *
+ * @note Whether or not unrecognized children are silently dropped or
+ * translated into text depends on the child definitions.
