I went back and looked at the terminology draft that is in last call. I 
assume that is where 'apex' came from.

However I'll claim that none of the language in that section of the 
document actually covers what is being described here, because this 
isn't about 'zones'...

FWIW, my sense is that the term zone has actually become quite ambiguous...
