                     Type of the navaid service. [AIXM 5.1]
                     This optional field may be used as a complement of the designator in order to achieve
                     unambiguous reference to the navaid.

            A named significant point, being either the site of a radio navigation aid or another
            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 navaid or 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. There are at least 5% duplicates/triplicates/even
            more…
            - 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:
            - For designated points: designator + position
            - For navaids: 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.
