Yes this is quite similar to what I had in mind. One thing I had
envisioned differently was to have sa.getPersistentAttributeType() ==
EMBEDDED translate as the attribute being an EmbeddedAttributeMapping which
gives access to what I think you mean by "physical info".
But other than that, yes I think we see it the same way.
