Depending on the type of DME, different accuracy is required.  In AIXM, the ElevatedPoint.verticalAccuracy attribute is provided for that purpose (according to 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)).

The ElevatedPoint.verticalDatum should be used to encode the corresponding information (e.g. 'EGM_96').
