is using attributes for microdata storage and as a selector a bad thing
<p>So I have a habit of using the attribute lang as my selector and store microdata,in jquery.</p>

<p>Althought it is not w3 compliant.But is it a good thing.
Also is there any alternative to this.</p>

<p>something like this. $('[lang=153]') to get this dom and $(this)[0].lang to get the data.</p>
