Re: plain and datatyped literals - DL happy with 1 property for both?

Yes. An owl:DatatypeProperty can take any value from LVi (the set of 
literal values, the extension of rdfs:Literal).

The RDF-compatible OWL semantics says that LVi contains plain literals, 
plain literals with language tags and typed literals with supported 
types (which includes rdf:XMLLiteral). The DL conditions require that 
LVi be distinct from all the other sets (IOT(individuals), IOC(classes) 
etc) but don't preclude use of plain literals that I can see.
