 			<p>Some plugins may choose to dynamically break a page's content into separate navigable pages, which can then be reached via deep links. One example of this would be the Listview plugin, which will break a nested UL (or OL) into separate pages, which are each given a data-url attribute so they can be linked to like any normal "page" in jQuery Mobile. However, in order to link to these pages, the page that generates them must first be requested from the server. To make this work, pages that are auto-generated by plugins use the following special data-url structure:
 			<code>&lt;div data-url="page.html&amp;subpageidentifier"&gt;</code></p> 
 
-			<p>So, for example, a page generated by the listview plugin may have an data-url attribute like this: <code>data-url="artists.html&amp;ui-page=listview-1"</code></p>

 			<p>When a page is requested, jQuery Mobile knows to split the URL at "&amp;ui-page" and make an HTTP request to the portion of the URL before that key. In the case of the listview example mentioned above, the URL would look like this: http://example.com/artists.html&amp;ui-page=listview-1
 			...and jQuery Mobile would request artists.html, which would then generate its sub-pages, creating the div with data-url="artists.html&amp;ui-page=listview-1", which it will then display as the active page.</p>

 			<p>The title text is normally an H1 heading element but it's possible to use any heading level (H1-H6) to allow for semantic flexibility. For example, a page containing multiple mobile 'pages' may use a H1 element on the home 'page' and a H2 element on the secondary pages. All heading levels are styled identically by default to maintain visual consistency.</p>
