That doesn't seem like a good idea.  In all species of OWL, every *instance* of 
an owl:Class is an owl:Thing.  But only in OWL Full can an owl:Class itself be 
considered an owl:Thing.  And even in the context of OWL Full it would be 
rather perverse to use "Thing" as a general synonym for "Class" (as you seem to 
be suggesting), at is muddies the distinction between classes and other kinds 
of things in the OWL universe.    (02)
