I think that's overstating the situation a bit. I don't think this WG
made any decisions about hGRDDL. (All our decisions are
in our meeting minutes; if I'm forgetting one, a pointer will
refute my claim conclusively.)

Just use the normal GRDDL markup, just like the Atom/turtle test
case and our decision on issue-output-formats shows.
An RDFa document is a serialization of an RDF graph just like a
turtle document is, no?

Is that stuff really not specified to your satisfaction?
