Jquery attribute purpose? Blocking referrer!

Jquery attribute purpose? Blocking referrer!

I was wondering what jQuery uses these attributes for inserted into the anchor tags (i.e. jQuery1250190927174="40")? I am able to modify the code using IE Developer Tools. On the links, I get a referrer if I remove the jQuery attribute (which is inserted dynamically) from the anchor tags. Example below:

<a class="external new-window" href="http://www.google.com/" jQuery1250190927174="40">

So what's the purpose of this attribute and how do I debug the referrer issue or better yet fix it? I only have this issue in IE, FF is fine!

Thanks
