I am seeing jQueryXXX="YY" attributes added to some of my DOM elements
<p>When I use the IE developer tools, some of the DOM elements have attributes added that are of the form
   jQueryXXXXXXXXX="YY"
where XXXXX is a fairly long digit string and YY is a usually small integer value.</p>

<p>I don't see these with the DOM inspector on Safari. </p>

<p>Why and when are these added? Is the data useful to me in any way?</p>
