I can't make the jboss_5_0.xsd, namespace restrictions and model fit together. The spec xsds don't expose any elements, so the only way to use an element in another namespace is by using a ref on a group or by extension. This leads to very weird constructs:<?xml version="1.0"?>

All elements directly under service are in jboss namespace, I could make an extension on session-beanType, but that would throw the model into a fit.
ejb-ref and ejb-local-ref are pretty consistent.
security-identity somehow defies the xsd I've defined for it, but fits the model.
Then wickedness ensues: resource-ref can't be an extension, because it redefines the usage of mapped-name. It should however be an extension (as resource-env-ref) because now description won't fit the model.
It leads to a mapped-name from a different namespace as shown in message-destination-ref. And thus I can't fit both of them into one unified model. So currently I'm at a stalemate.
Any suggestions?
