Seems like in one case you're making a statement about a portion of the
document (<div role="xf:hint">), but in the other you're making a statement
about something that the portion of the document somehow represents or
refers to (<div role="foaf:Person">). Is there a way to distinguish between
those cases? If not, maybe role can't serve two roles and you'd be better
off with some other shorthand to deal with the latter case.
 
Best,

Geoff
