If the use of owl:imports and owl:Ontology is not central to Jeremy's 
concerns, then let him put forward an example illustrating his concerns that 
does not use OWL vocabulary.

That is the essence of the reply, couched in W3C WG-speak.

It is obvious that the use of OWL is not central to the point that Jeremy is making here; but in any case, the issue concerns the relationship between an IRI used as a graph label in an RDF Dataset, and the same IRI used to refer inside RDF, and this matter is outside the scope of the OWL WG.
