+                <p>
+                        This sample page demonstrates the idea of Advanced Content Filter
+                        (<abbr title="Advanced Content Filter">ACF</abbr>), a sophisticated
+                        tool that takes control over what kind of data is accepted by the editor and what
+                        kind of output is produced.
+                </p>
+                <h2>When and what is being filtered?</h2>
+                <p>
+                        <abbr title="Advanced Content Filter">ACF</abbr> controls
+                        <strong>every single source of data</strong> that comes to the editor.
+                        It process both HTML that is inserted manually (i.e. pasted by the user)
+                        and programmatically like:
+                </p>
+<pre class="samples">
+editor.setData( '&lt;p&gt;Hello world!&lt;/p&gt;' );
+</pre>
+                <p>
+                        <abbr title="Advanced Content Filter">ACF</abbr> discards invalid,
+                        useless HTML tags and attributes so the editor remains "clean" during
+                        runtime. <abbr title="Advanced Content Filter">ACF</abbr> behaviour
+                        can be configured and adjusted for a particular case to prevent the
+                        output HTML (i.e. in CMS systems) from being polluted.
+
+                        This kind of filtering is a first, client-side line of defense
+                        against "<a href="http://en.wikipedia.org/wiki/Tag_soup">tag soups</a>",
+                        the tool that precisely restricts which tags, attributes and styles
+                        are allowed (desired). When properly configured, <abbr title="Advanced Content Filter">ACF</abbr>
+                        is an easy and fast way to produce a high-quality, intentionally filtered HTML.
+                </p>
+
+                <h3>How to configure or disable ACF?</h3>
+                <p>
+                        Advanced Content Filter is enabled by default, working in "automatic mode", yet
+                        it provides a set of easy rules that allow adjusting filtering rules
+                        and disabling the entire feature when necessary. The config property
+                        responsible for this feature is <code><a class="samples"
+                        href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">config.allowedContent</a></code>.
+                </p>
+                <p>
+                        By "automatic mode" is meant that loaded plugins decide which kind
+                        of content is enabled and which is not. For example, if the link
+                        plugin is loaded it implies that <code>&lt;a&gt;</code> tag is
+                        automatically allowed. Each plugin is given a set
+                        of predefined <abbr title="Advanced Content Filter">ACF</abbr> rules
+                        that control the editor until <code><a class="samples"
+                        href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
+                        config.allowedContent</a></code>
+                        is defined manually.
+                </p>
+                <p>
+                        Let's assume our intention is to restrict the editor to accept (produce) <strong>paragraphs
+                        only: no attributes, no styles, no other tags</strong>.
+                        With <abbr title="Advanced Content Filter">ACF</abbr>
+                        this is very simple. Basically set <code><a class="samples"
+                        href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
+                        config.allowedContent</a></code> to <code>'p'</code>:
+                </p>
+<pre class="samples">
+var editor = CKEDITOR.replace( <em>textarea_id</em>, {
+        <strong>allowedContent: 'p'</strong>
+} );
+</pre>
+                <p>
+                        Now try to play with allowed content:
+                </p>
+<pre class="samples">
+// Trying to insert disallowed tag and attribute.
+editor.setData( '&lt;p <strong>style="color: red"</strong>&gt;Hello <strong>&lt;em&gt;world&lt;/em&gt;</strong>!&lt;/p&gt;' );
+alert( editor.getData() );
+
+// Filtered data is returned.
+"&lt;p&gt;Hello world!&lt;/p&gt;"
+</pre>
+                <p>
+                        What happened? Since <code>config.allowedContent: 'p'</code> is set the editor assumes
+                        that only plain <code>&lt;p&gt;</code> are accepted. Nothing more. This is why
+                        <code>style</code> attribute and <code>&lt;em&gt;</code> tag are gone. The same
+                        filtering would happen if we pasted disallowed HTML into this editor.
+                </p>
+                <p>
+                        This is just a small sample of what <abbr title="Advanced Content Filter">ACF</abbr>
+                        can do. To know more, please refer to the sample section below and
+                        <a href="http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter">the official Advanced Content Filter guide</a>.
+                </p>
+                <p>
+                        You may, of course, want CKEditor to avoid filtering of any kind.
+                        To get rid of <abbr title="Advanced Content Filter">ACF</abbr>,
+                        basically set <code><a class="samples"
+                        href="http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-allowedContent">
+                        config.allowedContent</a></code> to <code>true</code> like this:
+                </p>
+<pre class="samples">
+CKEDITOR.replace( <em>textarea_id</em>, {
+        <strong>allowedContent: true</strong>
+} );
+</pre>
+
+                <h2>Beyond data flow: Features activation</h2>
+                <p>
+                        <abbr title="Advanced Content Filter">ACF</abbr> is far more than
+                        <abbr title="Input/Output">I/O</abbr> control: the entire
+                        <abbr title="User Interface">UI</abbr> of the editor is adjusted to what
+                        filters restrict. For example: if <code>&lt;a&gt;</code> tag is
+                        <strong>disallowed</strong>
+                        by <abbr title="Advanced Content Filter">ACF</abbr>,
+                        then accordingly <code>link</code> command, toolbar button and link dialog
+                        are also disabled. Editor is smart: it knows which features must be
+                        removed from the interface to match filtering rules.
+                </p>
+                <p>
+                        CKEditor can be far more specific. If <code>&lt;a&gt;</code> tag is
+                        <strong>allowed</strong> by filtering rules to be used but it is restricted
+                        to have only one attribute (<code>href</code>)
+                        <code>config.allowedContent = 'a[!href]'</code>, then
+                        "Target" tab of the link dialog is automatically disabled as <code>target</code>
+                        attribute isn't included in <abbr title="Advanced Content Filter">ACF</abbr> rules
+                        for <code>&lt;a&gt;</code>. This behaviour applies to dialog fields, context
+                        menus and toolbar buttons.
+                </p>
+
+                <h2>Sample configurations</h2>

+                <p>
+                        By default, CKEditor automatically localizes the editor to the language of the user.
+                        The UI language can be controlled with two configuration options:

+                        defaultLanguage</a></code>. The <code>defaultLanguage</code> setting specifies the
+                        default CKEditor language to be used when a localization suitable for user's settings is not available.
+                </p>
+                <p>
+                        To specify the user interface language that will be used no matter what language is
+                        specified in user's browser or operating system, set the <code>language</code> property:
+                </p>

+                        (<code>size</code>, <code>face</code>) will be replaced with XHTML compliant code.

+                <p>
+                        To add a CKEditor instance outputting valid XHTML code, load the editor using a standard
