How do I create an EAttribute whose data type is not an EMF class?

Question

Using EMF, I\'d like to define an attribute whose data type (EType) is external to my EMF model. That is, the type I want is a normal hand-coded Java class that is not part of m

You can add a data type to eCore models by manually adding an eClassifiers entry to the *.ecore file. (I was unable to find a mechanism to do this through the Eclipse UI.)

For example:

This will make the class available as an option for the EType in the Properties editor for EAttributes. It does not appear to make it available for EReferences.
