And I think it is the way to go. Besides, I am not sure how the
extensions we are planning to include in OWL 1.1. will behave in terms of
RDF compatibility anyway, and it is also unclear whether we should consume
our energies and time trying to find that out.

SWRL does not have an RDF-compatible model theory at the moment.

I don't think so
