So class="vcard" namespaces the terms because it encloses it. Sort of 
like data islands.

I don't think that's the problem, or you're missing the point in your 
eagerness to dismiss this issue. The consequences of what you're saying 
is that mf.org has laid claim to the wrapper class names so no-one can 
ever use them in their markup to mean anything else, across the whole 
web for all time.

Why not use something that is known to be unique instead of guessing?
