This is an example of the confusion between the identifier and a reference.
This confusion is really exacerbated by this awful term "absolute URI
reference" for
the identifier!

A QName is a perfectly good reference to something which is
identified by a URI.  The QName isn't itself a URI, just as a relative
reference a not a URI.
