You might try something like
inv: self.<whatever-identifies-the-special-class-type> implies
notation::Diagram.allInstances()->exists(element = self)
but that depends on what the scope of 'allInstances' is. In Papyrus,
for example, it would have to be the ResourceSet because Papyrus stores
the diagram content in a different resource than the UML content.
