I am happy with this, and I think it nicely resolves the raised issue.

The general question of whether the versionIRI should always reference an OWL file regardless of content negotiation or not is NOT a blocker.  I am curious because I am thinking of publishing other ontologies I work on using such a scheme.  If the OntologyIRI and or versionIRI ~MUST~ reference some form of RDF/XML regardless of content negotiation than I will have to re-think my plan.
