This is not a meaningful concept.

An XML namespace is a name, conventionally a URI or IRI, that can be
associated with one or more names used in a document for two main
purposes -
(1) to disambiguate elements or attributes that might otherwise have the
same name;
(2) to identify an XML vocabulary (and perhaps also its creator).

If you mean, using RDF to validate that an XML instance conforms to a
particular definition of an XML vocabulary, then really you are using
RDF to validate XML documents, perhaps as an alternative to a DTD or
RelaxNG or W3C XML Schema.

I don't know why you would want to do this; in particular, be careful
not to introduce unintended "semantics", for example by associating a
name in an XML document with a URI in a way not expected by whoever
created the vocabulary and/or document.

Note that it is _not_ intended that namespace URIs be dereferenced.
