Also PANS-AIM ENR 4.1 states as requirement
elevation of the transmitting antenna of DME to the nearest 30 m (100 ft);

In PANS-AIM Appendix 1 the accurcy depend on the type of DME, for DME/P it is 3 meters. |
The diagram below shows the AIXM classes, including the relevant data types, needed to encode that information The main class is the DME which is a specialisation of the NavaidEquipment.
...
Depending on the type of DME different accuracy is required. In AIXM the ElevatedPoint.verticalAccuracy attribute is provided for that purpose. (According PANS-AIM Appendix 1, Table A1-5, for DME.type equal-to 'PRECISION' 3m accuracy is required for all other types it is 30m (100ft)).
Navaid Component
VOR/DME
A DME may be co-located with VOR. Such a VOR/DME will be coded as a Navaid with two correspondning NavaidEquipment instances, a VOR and a DME.
For both NavaidEquipment the NavaidComponent.collocationGroup will be equal-to '1'.
If the VOR is the navigable location of the navaid when the navaid is used as significant point:
the NavaidComponent.providesNavigableLocation for the VOR will be equal-to 'YES' and the NavaidComponent.providesNavigableLocation for the DME will be equal-to 'NO'.
The VOR provides the bearing information, whereas the DME is used for the distance information.
