As a matter of fact I don't see RDFa using @profile.

The Web Linking draft does not override anything in HTML 4.01. It just 
states that generic link relations are a good idea, creates an IANA 
registry for them, and defines how to use them in the HTTP Link header.

That being said I *do* believe that it's an incredibly bad idea on using 
the same relation name for different things.
