Sorry, Jonas, I skimmed the vital three lines in your original email and
missed the key point that fixes my four examples:

With this point noted, I retract my scatter-gun comments and extend an
apology instead.  RDFS prohibits anything being a subclass of a literal, so
my first two examples go away.  RDF also prohibits using a literal as a
domain, so my third and fourth examples go away.  Neat!

Now all we need to do is to define { xsd:element rdfs:subClassOf
rdfs:Literal } in some appropriate place.
