[hibernate-dev] @MappedSuperclass, @Embeddable and consistency

The JPA spec is completely silent on inheritance when it comes to embeddable classes. When Emmanuel was first developing hibernate-annotations we decided to allow the use of @MappedSuperclass to be extended to embeddable classes to control the persistence of attributes when an embeddable had a superclass. I want to make sure we are all supporting this consistently. And if not, whether we need to revisit that original decision. For example, Gail has recently found inconsistencies in regards to how envers handles @MappedSuperclass + @Embeddable, compared to ORM. Specificaly it has different expectations for audited attributes for @MappedSuperclass when it comes to @Entity versus @Embeddable. Adam/Lukasz. do you guys see that as a conscious decision? If so, can you validate why y'all decided to go that way? If it was not a conscious decision, are there major technical/implementation hurdles to overcome in making this consistent? In Search, OGM, etc are we consistent with this interpretation of @MappedSuperclass + @Embeddable?
