Hi John,
I see your point about coordinate variables. However it would be nice
to be able to say "aggregate over all non-coordinate variable".
Unless there's something I'm missing, I would have thought that this
was a very common case.
Thanks, Jon

Hi Jon:
How do you distinguish between variables that should be aggregated and
those that shouldnt? for example, often adding a time dimension to the
coordinate variables screws things up for some software.
