It may be used in other vocabularies, yes, but those vocabularies will
likely have to choose how to include it.

Right, and the latest draft also uses the same language:

The syntax can be defined independently of how one follows one's nose,
right? We hope it will taken up by other XML languages, but really HTML
is the main target right now.

it would definitely have to be part of the schema for the XML language
you're thinking about. For example, it could well be done using a GRDDL
transform specified in the namespace document.

Right, so you still need access to HEAD/PROFILE, right? Since that value
of PROFILE will be different from one application to another, obviously
(unless it's the RDFa transform, for example... but then we're back to
our use case :)
