Not duplicating effort and making sure we are integrating the sources of metadata is the point here, so I don't think we have reinvented the mdr as yet. So for the jndi binding policy, we have: - aop.xml providing a bean level/aop domain level default. - deployer level defaults. - class level annotation, jboss.xml providing deployment level specifications that go into a JBossMetaData.getJndiBindingPolicy So the mdr should be the authoritative view of the JndiBindingPolicy with loaders from the various sources?
