I'm playing with EML now Dimitrios. Something doesn't seem right
however. When I try to merge the MergeOO example only the <Models> rule
matches, and the resulting Merged.model is simply a union of *all* the
elements in both models. I end up with duplicate School and Teacher
classes, and String Datatypes.
I was expecting something more like I see explained in the example at
http://dev.eclipse.org/viewcvs/indextech.cgi/org.eclipse.gmt/epsilon/org.epsilon.eclipse.help/index.html
For reference I've pasted in the text view of the output model:
