This is the key point, but I think it's perhaps one that's a general
issue for the CF guys to sort out rather than something we need to deal
with when proposing a standard name. One could include a short snippet
in the description along the lines of "For this variable to be
meaningful, it must be associated with a {horizontal|vertical} datum.".
Again, one should approach this point carefully as it's likely to cause
a torrent of discussion and bog that name down in a swamp of
difficulties. At the least, try to isolate it from others or, if the
discussion starts, try your hardest to separate the datum issue into
another thread separate from the name proposal!

Hear hear!
