@JonathanGregory If "string front_type(front_type)" could be considered a valid auxiliary coordinate variable, I'd be fine with that. In fact, I think that is a great approach.
The message I have gotten repeatedly from this discussion is that there were strong feelings that this should not be allowed. I agree that, whatever flaws there may be in the current language, CF currently disallows non-numeric dimension coordinate variables. As far as it goes, I don't think we should define a collating order if we allowed string dimension coordinate variables. In fact, I think that would be the wrong way to approach it. -- You are receiving this because you are subscribed to this thread.
