I haven't had much need to refer to ICAO's Pans Rac document, but I'm sure there used to be a reference to PAN in there. Compliance with a Pans document is not mandatory, but if it isn't fully implemented, the State must notify the fact in its AIP. If "Manuel's" country has done so, I feel sure that Jeppesen, and other such service providers, will have detected it and made relevent notes for its clients.
I wonder if the FAA uses the term in its publications? Does it appear in Jar-land documents? If there is significant inconsistency in this, then maybe the matter should be raised with your local ALPA rep., to take up with IATA who, in turn, will (or should) take it up with ICAO and the State concerned, as a matter related to aviation safety.
Or maybe I'm just living in Disneyland after all...
