[hibernate-dev] metamodel work

I remember you mentioning that we may keep Configuration for a short time bridge. It seems to me that we would want a way to switch tests between the different sources of metadata.

I'm confused why you would say it's only pertinent for "tests of functionality/features that have not yet been implemented in metamodel branch". Are you saying that you'd only use hibernate.test.new_metadata_mappings=true to find out what fails?

I write new tests that extend BaseCoreFunctionalTestCase and set hibernate.test.new_metadata_mappings=true to confirm that functionality that has been piped into the persisters is working. If one of these tests fails somewhere down the line, that means that something in the metamodel or the persister code broke.
