/**
 * A DeleteAll annotation is specified to indicate that when an relationship 
 * is deleted, it should use a delete all query.  This typically happens if the
 * relationship is PrivateOwned and its owner is deleted.  In that case, the members
 * of the relationship will be deleted without reading them in.
 * 
 * Use this annotation with caution.  EclipseLink will not validate for you whether the 
 * target entity is mapped in such a way as to allow the delete all to work.
