It doesn't REQUIRE it, but it sure would be much neater if they could be.

Well, this is true insofar as RDF literals are concerned, but
not "literal data values" in general, per se.

One can encode typed data literal values in URVs (URIs) and
in such a form one has explicit data typing information about
the value (think of the URV as a complex data object with
embedded type identity in a weakly typed system) -- and thereby
those values can also serve as subjects of statements because
they are proper resources.

And no changes to RDF are required. Only perhaps some rules
of interpretation and/or equivalence between such URV forms
and qualified anonymous nodes specified for rdf:type (such
as defined in my X-Values concept).
