[hibernate-dev] metamodel work

I've been re-thinking what I wrote in my response below and would like to clarify some points.
I'm going to move the tests that that I added to src/matrix to src/test. These tests are for simple use cases (e.g., unidirectional one-to-many, no subclasses, no join tables, ...) and are not database-dependent.
I would like to be able to run these tests (that I move to src/test) using both the old and new types of metamedata so I can:
1) ensure that the test passes for both types of metadata;
2) detect at a later date if some change was made that broke the test for either type of metadata;
3) easily compare the SQL that gets generated from both types of metadata to see if there are any differences; if there are differences, at this point (at least), they'd probably be due to something not yet implemented in the new metamodel.
I'd like to be able to run all the "test" tests (i.e., excluding the "matrix" tests) using hibernate.test.new_metadata_mappings set to true. Currently, there are 29 failures. It would be nice to be able to indicate (e.g., using an annotation) that a test is expected to fail using the new metamodel.
As "gaps" are filled in, it would be nice to be able to the same for the src/matrix tests.
In the future, as new functionality is added that only works using the new metamodel, it would be nice to be able to indicate that a test is expected to fail using the old Configuration metadata.
