Dave,
Thank you for responding.

Two points should be made:
o The descriptions of the relations on the value spaces of Schema
datatypes are normative for schema processing but are advisory
for other applications.
I'm not really asking about *processing*. Schema defines the value
spaces of its primitive datatypes to be sets. We need to know what are
in those sets.
I guess there is another way to ask the question. Given:
S = the value space of xsd:string
U = the value space of xsd:anyURI
L = the set of RDF plain literals that have no lang tag, i.e.the set
of sequences of UNICODE characters
Is S intersection U empty?
Is S intersection L empty?
