| * A CompositeMember annotation is ignored unless is in composite member persistence unit. |
| * It may be used in conjunction with a ElementCollection and CollectionTable annotations. |
| * It should be used if target type is a primitive type |
| * and CollectionTable designates the table that belongs to |
| * composite member persistence unit other than the source composite member persistence unit. |
| * That allows the source and target to be mapped to different databases. |
