I think it's important to enumerate the values in
machine-readable form, using instances (preferably) or XML
Schema.  I don't think the set of values needs to be closed
(i.e. we can use an allValuesFrom Restriction instead of a
oneOf).

I do prefer the alternative approach of subclassing
owl:Ontology [1], in part because it requires less language
vocabulary (3 subclasses vs. 3 instances, 1 Class, 1
property, and 1 Restriction).
