RDF namespace declarations *may* (and even perhaps should) point to
RDF schemas, which are not XML schemas at all.  They declare
RDF classes and properties, not XML elements and attributes.

Both RDF statements and RDF schemas are normally represented in XML,
but other representations (graphical) also exist.
