The most detailed discussion I could find was
(BTW, IMO the practice of charging for standards documents (as the ISO
and IEEE etc do) in hard copy form is understandable, but charging for
.pdf versions is perversely contrary to the purpose of wide dissemination
necessary for wide adoption. IOW, IMO they ought to think of another way to
get funded).

Anyway, the 'T' looks to me to be optional by mutual agreement between
particular information exchangers, but otherwise required?
