030 * As of ISO 19115:2014, the {@code RS_Identifier} type has been merged with its {@code MD_Identifier} parent type.
031 * Consequently in GeoAPI 4.0, all usage of this {@code ReferenceIdentifier} interface will be replaced by usage of
032 * {@link Identifier}, and this {@code ReferenceIdentifier} interface will be deprecated.
