OWL.Thing is a Resource.  The OWL standard says "Declaration( Class(
owl:Thing ) ) " is a declaration of this built-in entity, but a class
cast (OntClass) OWL.Thing fails.  The following also fails.

Resource owlThing = OWL.Thing;
OntClass classThing = owlThing.as(OntClass.class);

Is there a way to get OWL.Thing as an OntClass?
