I'm facing the following mutually exclusive requirements:
1. I need to have the class model in EMF XMI (ecore), and therefore I'm limited in creating it with the EMF Class Diagram Editor.
2. I also need the functionality of the UML Class Diagram Editor where I can extend a class with a superclass that is outside the class diagram. I would also like to display this inheritance relationship it in the diagram file.

The EMF Class Diagram Editor seems to be "less-featured" compared to the UML Class Diagram Editor.
More specifically: the UML Class Diagram Editor has a more verbose "New Class" wizard that allows the user to specify superclasses.
In contrast, the EMF Class Diagram Editor has a limited "New Class" wizard that doesn't give me the capability to specify superclasses!

Any workarounds on this issue?
i.e.
- How can I inherit from an outside class from within the EMF Class Diagram Editor?
- Better yet, how can I open a diagram file with the UML Class Diagram Editor while it has been created with the EMF Class Diagram Editor?


Your feedback is greatly appreciated.
