But there is usually some way to use other HTML5/WF2 features without 
breaking current browsers. The only way I can see to do this with href 
on many elements is to manually walk the DOM inserting <a href="bar" /> 
elements as children of the <foo href="bar" /> elements, with some care 
needed for elements such as <tr> that really won't take <a> as a child. 
Authors doing this would also have to be very careful about not breaking 
their CSS rules etc. in current browsers.

href on multiple elements is a nice idea but I'm not sure the benefits 
outweigh the costs.
