I am assuming that an RDF/OWL application dereferences using:

Accept: application/rdf+xml

In the context of the media type "application/rdf+xml" the returned
representation is to be interpreted as RDF
http://www.w3.org/TR/rdf-concepts/#section-Social

One could request/return a media type "application/xml" in which case the
RDF/XML would be interpreted as XML i.e. without the RDF semantics. It is in
this later case (or other media types besides application/rdf+xml, and
related media types such as "application/n3" or "application/n-triples")
where current SW agents cannot derive meaning
