It would be useful to not only consider what @profile may have been 
intended to do years ago, but what it actually *can* do in practice. 
(That would also be useful with respect to the discussion in the HTML 5 WG.)

If I follow your argument, no new relation names can be used in HTML 4, 
except by using a profile. We have evidence that this is not true. For 
instance, consider rel="nofollow".
