Surely we have to do something like this, for what is one to do when faced with some RDF containing literals typed iwth an unknown datatype? You don't know if they are ill-formed or not. So I think we have to say that such literals are treated simply as denoting unknown objects in the universe.

Well, the D in D-entailment is a parameter, right? What we actually have are things like XSD-entailment and {xsd:number, xsd:date}-entailment, and so on for other sets of datatypes. The datatypes in the set D are the ones recognized by the entailment regime.

I think so as well.

Exactly.
