But if the user agent would be reading the profile attribute value 
and - as HTML 4 says - "perform some activity based on known 
conventions for that profile", then one could have a two step 
solution in text/html as well.

The problem is establishing the convention. May be the convention 
could be to link unknown profile IRI to the CURIE via a <link> 
element.
