Thanks very much David for the info on this topic.
Still have several questions.

This old email has some related info:
There already are JAXB objects for old/new descriptors and as a result the schema is rarely updated. I think for a while we didn't even have one.
There's a bit of legacy here in the for a short bit (Geronimo 1.0/OpenEJB 2.0) OpenEJB was not really a separate project in any technical sense. The OpenEJB 3.x codebase returned to being more standalone. The reason to keep the v2 openejb-jar.xml format was it was made 100% for Geronimo -- it has all the Geronimo dependency and config stuff in it amongst other things.
Anyway, here are the root JAXB objects for the related trees:
openejb-jar v2: http://svn.apache.org/repos/asf/openejb/trunk/openejb3/container/openejb-jee/src/main/java/org/apache/openejb/jee/oejb2/OpenejbJarType.java
Here's the newer non-geronimo-specific openejb tree:
In terms of what we should do now with a new major Geronimo version, I suspect it will largely depend on David J's work. Seems like there'll be a very big and very not backwards-compatible change with regards to parents/childern and dependency information. Not sure what our plans are with regards to backwards compatibility of existing descriptors.
