In short, I think it most of all is the result of an attempt to 
solve a conflict with Ian ...

Even if it strictly speaking is a separate issue, I also think 
that @rel=profile intendeds to solve/clarify the "can there be 
more than one profile uri" unclarity of HTML 4. (The "significant 
profile" issue of HTML 4: "even though this specification only 
considers the first URI to be significant")

Good points.

Also: it has repeatedly been raised some conceptual points by some 
in the GRDDL/RDFA league in favor of <head profile="">, namely 
that the profile should be defined *before* the content of the web 
page is handled by the tool/parser/ua/etc. That objection is, in 
fact, related to the "significant profile issue".
