| /** |
| * A {@link DataIntegrityException data integrity exception} that indicates an attempt to create <i>stale references</i>. |
| * A stale reference is a refenrence that points to a target object that does not (or no longer) exist. |
| * <p> |
| * Detection of referential integrity violations must be explicitely enabled on the server side because it can be expensive: |
| * |
| * <pre> |
| <property name="ensureReferentialIntegrity" value="true"/> |
| * </pre> |
| * The risk of referential integrity violations can be <b>reduced</b> (but not eliminated) by using local cross reference queries |
| * before committing: |
