That's unfortunate, though I see why, in pure RDF land, this is a  
good idea.

It might be interesting to think about simpler RDF properties for  
these kinds of tools, RDF properties that mirror the MF properties  
more closely. I'm thinking this is especially possible since the  
vCard clients can already consume the literal we're thinking about.

Yeah, that seems like an abuse of type inheritance....

Fixed the reference.

So, not sure how to proceed on this one. It seems like some simpler  
RDF properties would be useful, especially if the existing tools can  
already handle the literal we want. What do you think?
