Re: head/@profile needed in HTML 5? GRDDL in Linked Data community?

As someone who's implemented a pretty poor grddl library, I'd have to say
for real world use, profile isn't needed - it's assumed a lot of the time.

Practically no authors respect it regarding microformats and friends. I
found much utility coming from explcitly saying "search this document for
vocabulary X".

Most of my implementations were around microformat parsing.

Right now it sits in the "I wish people used it properly' category for me.
