aside:  I still don't see how in one breath you can say that use with  
RDFa requires all @rel/rev values to be CURIEs and in the next breath  
say you can mix and match RDFa and microformats.

On the other hand, as far as it affects the discussion of WAI-ARIA in  
the extensible metadata attributes paragraph, it all looks fine to me.
