Yes, good idea. One also needs to define the tab order of the "groups".

But tables, divs, spans are not normally focusable.

True.

But I don't believe many sites will break because of this. Remember many  
web developers don't really care about types. They don't even know much  
about them. IMHO the number of sites that might break makes these cases  
neglectable.
