As far as I could see you are not misunderstanding this. And I am not
100% sure how we would handle that. The mechanism that does come to my
mind is a hack. Indeed, let us consider we have defined some sort of a
keyword mechanism via, say, the @profile attribute. I could then imagine
setting up a process somewhere that regularly looks a the RelExtensions,
would somehow scrape that page, and produce a @profile files according
to the syntax that we would define. The URI for that generated @profile
would be well-known and could then be used by HTML5+RDFa authors.

Just my 2 cents...
