Yes, but how does this help in this case?

If I have

   <head profile="http://example.com/ http://example.org/">

and

   <a rel="foobar">

...how do I find out which profile/namespace foobar belongs to? It 
doesn't solve the disambiguation problem.

I think it would be easier to convince them if you wouldn't have 
unilaterally changed the semantics for the rel attribute (note that I 
have less problems with CURIEs in *new* attributes).
