 * @param javadoc
 *      Additional javadoc that will be added at the beginning of the

 * @param members
 *      A map from enumeration values (as String) to BIEnumMember objects.
 *      if some of the value names need to be overrided.
 *      Cannot be null, but the map may not contain entries
 *      for all enumeration values.
 * @param loc
