Pre-rendered collapsible content on jQuery Mobile demo fails to validate with W3C

Pre-rendered collapsible content on jQuery Mobile demo fails to validate with W3C

I just ran this through the w3c validator:


Line 230, Column 50 Element div not allowed as child of element a in this context. 
…<div class="ui-collapsible-heading-status"> click to expand contents</div>
I was going to use the pre-rendered content, but there seems to be an issue here?
