Matthias,
Nested packages are evil, and no, we generate nothing for an empty package:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=142856
Adding a "dummy" EDataType will force it to generate.
Is there is a compelling reason to have generated code that's not
capable of doing anything useful? It's hard to imagine...

Matthias,
You're best to avoid subpackages entirely and if you can't avoid that, a
dummy EDataType will do the trick.
