Martin,
I tend to agree with you. We have enough on our plates trying to deal with
standard names. The same goes with area types. I am assisting a group that
has > 200 of them. Are we really going to expand area types that broadly?
And when the next group has 100 slightly different types, what then? It
seems pretty clear that we need a scheme for referencing in some fashion
for these things, and drop the conceit that CF must be entirely
self-contained.
Grace and peace,
Jim
