However, as far as possible, the geographical designator XX should not be used.
(4)	For the geographical designator in the abbreviated heading of the METNO and WIFMA messages, XX should be used.
(5)	Geographical designators contained in this table should not be used in the abbreviated heading of bulletins containing ships’ weather reports and oceanographic data.
