However, I'd point out, in the last document, where they describe a
mapping of OWL 1.1 to RDF, they make the following caveat:
Not every OWL 1.1 ontology can be serialized in RDF. In particular,
ontologies using the following features of OWL 1.1 cannot be serialized:
1. punning and
2. annotations on axioms.
Please see a recent thread on the public-owl-dev mailing list about
this:
http://www.nabble.com/Limitations-of-OWL-1.1-to-RDF-mapping-tf2639224.html
Bijan states:
"The RDF mapping has lagged behind the others, but the plan is to
extend the mapping to cover these cases."
