Not exactly an open source tool. :-P

Yes. It was even nice that we could generate them in a binary
compatible way.

So you're using UML2...

Maybe UML2 has enumerations.

Unfortunately I'm not sure how to do either, and these days I haven't
got UML2 source in my workspace.
There's Ecore Tools which you can use to create diagrams directly for
Ecore; it's not as polished as IBM's produce though.

Here's a good way to get the tool to provide the answer. Take your
Ecore model, create a GenModel for it; from the context menu for the
resource using File->New->Other...->Eclipse Modeling Framework->EMF
Generator Model. Then open the Generator model, and from the context
menu of the root, use Export Model... to export it to UML2. I believe
that should produce a UML2 instance that, when reimported to Ecore, will
produce the original Ecore model again.
I'm pretty sure UML2 provides a specialized Ecore profile that's used to
record/specify details not directly specifiable in UML2; this will help
you discover it and how to use it.

Edmund,
Thanks for the details from your investigation. They will help the next
person who has the same problem!
