Do we want to include this in RDF?
RDF says:

"""Everything of the form "blabla"^^someURI can be the object of a 
triple."""

If we include rdf:plainLiteral in the spec of RDF, we then say:

"""Everything of the form "blabla"^^someURI can be the object of a 
triple *except* if someURI = rdf:plainLiteral."""

Which sounds weird. Or maybe this is optional, just to be considered for 
use with D-entailment?
