Two possible cases:

1. The range of a property (p)  is disjointFrom the range of another property (q). (This is supported by OWL DL)

2. Property p is a subproperty of the negation of property q. (But OWL doesn't support the negation of property)

Your example falls into the second case. It seems that there is no way by using OWL DL.

Any comment is welcome!
