Not quite the same. "name" in the quote above can be translated as
"URI". So when it says:

	"user agents may be able to recognize the name"

it means that user agents should only be doing this for URIs that they
recognise. Unless I'm misunderstanding your suggestion, RDFa processors
would be applying the profile as a default prefix whether or not they
recognised the URI.

I don't have anything against this general technique - but I don't think
it's consistent with the HTML4/XHTML1.x definition of @profile, so a
different attribute would need to be used.

A lot of the debate here has been on the syntax and model for profile
documents. Personally I don't think we've had enough debate on whether
profile documents are needed at all - Martin's suggestion here is not to
define a profile (in the sense that we've been talking about them) at
all, but to just set the default CURIE prefix. What exactly are the use
cases that show this to be insufficient? Personally, I don't think I've
seen any yet.
