OK, well caught. That *is* what I assumed, however some of my colleagues 
have assumed UNION. Perhaps it would be worth adding some text to 
clarify? Also, is it possible to 'close' the domain and/or range so that 
they cannot be modified subsequently? (In a similar fashion to the 
rdf:parseType syntax?)
