I am not a GIS expert, but my GIS friends constantly remind me that there is no such thing as latitude and longitude. Such numbers are dependent on the geodetic system used. Futher, the draft arbitarily uses wgs84 for altitude, so it may be that this is also intended to be used for latitude and longitude. This would not be acceptable in Australia, for example. In New South Wales, and Australian state, all candastre (land) data is supplied in a couple of Australian standard. So wgs84 locations would not correctly show which street you were standing. I suggest the standard needs to require the inclusion of the geodetic system. The standard may need to propose a list of supported geodetic systems.
