Thanks Alan, I had made a mistake of not realising that the subject line 
did specify stuff about the property p.

This suggests that we should have been talking all along about the 
explicitly typed literal having datatype (or even just rdf:type) being D.

p a rdf:Property ;
rdfs:domain rdfs:Literal ;
rdfs:range rdfs:Datatype .
_:x p xsd:int .
_:x owl:sameAs  "2"^^xsd:int .

And possibly

p rdfs:subPropertyOf rdf:type .
