Yes I am, but not because I don't like the profile mechanism, for many 
years I have hoped that @profile could be used in a pragmatic way,  but 
in the real world I suspect it will be little used because there is much 
more value embedding meta-data in the page itself than referencing an 
external document, think microformats and its @profile usage which is 
almost none existent in the "real world" despite how much you promote 
its use, old habits die hard :)

I don't know if RDFa1.1 *needs* something else @vocab and @prefix seems 
to cover most or all of my use cases, both attributes are very practical 
and useful where as @profile is perhaps more lazy-web so to speak and 
shouldn't really be encouraged in web-standards.

No problem ;)

Best wishes.
