 *  <xsd:complexType name="RollbackType">
 *      <xsd:complexContent>
 *          <xsd:extension base="wfs:NativeType">
 *              <xsd:sequence>

 *                          The difference filter will be used to compute a diff to be applied
 *                          in order to perform the rollback. A rollback is conceptually just
 *                          a Transaction applied on the result of a back-diff between two
 *                          revisions.
 *                       </xsd:documentation>
 *                      </xsd:annotation>

 *              </xsd:sequence>
 *              <xsd:attribute name="handle" type="xsd:string" use="optional">
 *                  <xsd:annotation>
 *                      <xsd:documentation>
 *                       The handle attribute allows a client application
 *                       to assign a client-generated request identifier
 *                       to an Insert action.  The handle is included to
 *                       facilitate error reporting.  If a Rollback action
 *                       in a Transaction request fails, then a Versioning WFS may
 *                       include the handle in an exception report to localize
 *                       the error.  If no handle is included of the offending
 *                       Rollback element then a WFS may employee other means of
 *                       localizing the error (e.g. line number).
 *                    </xsd:documentation>
