ISSUE-81 (reification, negative assertions): reification unwise in negative property assertions

http://www.w3.org/2007/OWL/tracker/issues/

Raised by: Jeremy Carroll
On product: 

The mapping rules for NegativeObjectPropertyAssertions and NegativeDataPropertyAssertions both use reification.

It would be possible to map these as membership of the complement of the appropriate hasvalue restriction - avoiding reification. Jeremy sees this as preferable, but might cause round trip issues
