I think that XPath is not expensive compared to RDF processing and
further translation machinery applied to ITS decorated sources.

You mean probably

#xpath(/html[1]/body[1]/h2[1])

Yes, this would be quite feasible.

We shouldn't overengineer. So if event SemWeb optimist (if I can call
you that way :-) have doubts about RDFa we might give it up. But it's
always good to have mapping to RDF.
