documentation
A named geographical location used in defining an ATS route, the flight path of an aircraft or for other navigation or ATS purposes. [FIXM]

The coded designator of a designated point is not always sufficient for unambiguously referring to that feature:
The 5-letter coded designator of a waypoint is supposed to be unique world-wide (according to ICAO Annex 11), but in reality it is not.

The combinations of fields that would make the references unique are name + position.

This FIXM class adds an optional properties 'position' which may be used as a complement to the 'name' information in order to remove any ambiguity on the coded designator.
