[hibernate-dev] ORM DDL doesn't reflect BV constraints with validation mode CALLBACK

[Steve Ebersole]

The reasoning is that the 2 BV modes you mention make no mention of also
applying constraints to the database.  It would be surprising for that to
happen.  I can see the argument for AUTO, but absolutely not for CALLBACK.

Also important is the distinction that hibernate accepts multivalued
validation modes, whereas BV does not if I remember correctly... Although
in my opinion it absolutely should.
