There is a discussion about XML overriding rules in Section 12.2 of the JPA 2.0 spec.
Are the following overrides possible?
1) Can an @Entity annotation be overridden using XML <mapped-superclass> or
<embeddable>?
2) Can a @Mappedsuperclass annotation be overridden using XML <entity> or
<embeddable>?
3) Can a @Embeddable annotation be overridden using XML <entity> or
<mapped-superclass>?
Supporting this would obviously affect the Hierarchical domain info.
If any of these overrides are valid, then we should discuss this at the Tuesday morning
meeting.
