[hibernate-dev] HHH-10622

[Steve Ebersole]

I believe the only things you can do via hbm.xml that you cannot do in
annotations are:

1) alternate (non-pojo) "entity modes".  Makes sense because you'd have
nothing to annotate, there would also be nothing to enhance
2) proper entity name support.  This is the feature where you can map the
same class multiple times using different entity names.  E.g. map the class
Account twice as "Account" and "DelinquentAccount".  Again this is
something that cannot be enhanced anyway.
3) property-ref proper.  JPA, and thus annotations, defines associations
based on columns rather than attributes.  But again this has no bearing on
enhancement.

Those are the only ones I can think of at the moment.  Maybe others can
chime in if they know of others.

And no, you cannot use hbm.xml and annotations to define parts of mapping
for the same entity the way you can with annotations and orm.xml.  In fact
that is the point of 7.0, we will move to an extended orm.xml schema as the
Hibernate-specific XML mapping.
