Model Registry Nature

The presence/absence of the Model Registry nature in a project determines whether the Model Registry Property Page appears as one of the Properties pages shown when Properties is invoked from the right button menu of a resource.

Invoking the right button menu on a project within Navigator or Package Explorer views activates a menu that contains either UMLX Natures->Add Model Registry Nature or UMLX Natures->Remove Model Registry Nature according to the prevailing usage.
