I don't see how.

First, I don't think it's possible to 'stray' into GRDDL...you really
have to want to go there!

Second, the mappings I've been describing are specifically of
predicate/object couplets. For example:

  <title> => dc:title
  @alt => rdfs:label

or whatever. GRDDL proposes completely transforming a document that
has no relationship to RDF into one that does.

(I'm not proposing these mappings -- as I've said, RDFa Core should
not be defining these. I'm just illustrating the simple level of
mapping that is needed to get from host language to RDF.)

By the way, I figured I could trim the CC list since your one-liner
didn't seem to be either a question or a reasoned argument.
