I tried sending this to the rdf-interest group but it doesn't seem to have
got through...

That is, unless the constraint that there can only be one rdfs:range is
relaxed [and allow disjunctive semantics], though this tantamounts to
blasphemy for the Logic Boys.

Anyhow, I don't recall the RDFS spec being too specific when it comes to
validating qualified values.  The level of indirection is usually provided
by an anonymous resource.  Should an author be required to specify the type
of this anonymous resource in order to validate the qualified value in
entirety with RDFS contraints, or should the qualification be more free-form
with any RDFS constraints on a property defaulting to the rdf:value portion
only?

The latter would solve your problem.  I personally don't have any strong
views on this, though the ability to do either would be nice.
