documentation
A radio navigation aid 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 navaid is not always sufficient for unambiguously referring to that feature:
The en-route navaids (VOR, DME, NDB) designator is supposed to be unique (according to ICAO Annex 11) within 600 NM. This means that these designators are not unique world-wide. For airport navaids, there is no limitation.

The combinations of fields that would make the references unique are designator + position + navaid service type.

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