/**
 * Use Case: IdClass identifiers declared across multiple mappedSuperclasses in an inheritance hierarchy.
 * Note: The following MappedSuperclass defines 3 of 4 of the Id fields as part of the IdClass MSIdClassPK.
 * The 4th field is declared on the subclass.
 * The IdClass annotation can go on the subclass or the entity but not on this root.
 * As long as resolution of all fields in the IdClass are available - the configuration is good.
