How does data binding with DOM element work?
<p>I am wondering, how jquery can associate arbitrary data with any DOM element without adding any HTML data attribute? </p>

<pre><code>$('#div_id').data('suffix',(count++)) ;
</code></pre>

<p>I don't see any data attribute associate with HTML element in firebug HTML snapshot.</p>

<p>What is the mechanism?</p>

<p>Although this data storage method is no longer needed in HTML5, still i am not clear actual mechanism of jquery data storage.</p>
