I'm making a slightly subtler point.  Microdata, RDFa, and even XML
Namespaces can all be processed with a generic processor that has no
information about the actual vocabularies being used.  You can just
say "Find me all the items/triples/namespaced elements on the page",
and it can do it.  Thus the extensibility granted by these
technologies is distributed, as no central authority has to recognize
and bless your vocab for it to be processable by generic tools.

However, if this proposal requires tools to recognize particular
@profile values before it can even tell that there *is* data embedded
in the page, let alone *extract* it, then this does not seem to be
distributed in any significant way.
