I understand that this a bit of an anathema to OWL but it's the sort of functionality we need to provide if we want RDF to be taken seriously in most industries. For example, a substantial fraction of medical informatics concearns with specification and enforcement of value sets.

It is certainly not anathema to OWL to specify value sets.  One can easily 
construct OWL restrictions for value sets, like
   all ex:property { ex:val1 ex:val2 }
A constraint interpretation of this construct would be that every value given 
for ex:property has to be either ex:val1 or ex:val2.  One can also require the 
existence of a value.
