The problem is that the previous spec didn't capture our intent, so you can
think of this as a new requirement if you prefer.

That's a good question, and I'm not sure we specify that. What we probably
should've required is that the ear-level alt-dd could be a jar file containing
both the application.xml and module-level deployment descriptors referenced by
alt-dd entries in that application.xml.

I'll file an RFE.
