The existing content negotiation is one of the reasons I suggested this.  It keeps uniformity by using content negotiation with both the latest (at http://www.w3.org/ns/prov ) and with the version tagged ontologies.

Is this from a spec? I know of several ontologies that are published and referenced via IRIs that provide both documentation in HTML and the ontology in RDF/XML via content negotiation from the same IRI; and we are already doing so with http://www.w3.org/ns/prov, so why should a versionIRI be treated differently from an Ontology IRI?
