Subject: A&C bit words
Status: O

From talking to Doug Hunt, I was convinced that it would be good to have
the RFC say something like "you may use the A&C bits, but if you do, you
should be aware that a transmitting station may not see its recently
transmitted packet until it has transmitted several other packets and
released the token, and that bridges may do evil and dastardly things to
A&C bits"  (or words to that effect).

I agree with the sentiments that the A&C bits are useless and stupid.
However, anyone who wants should be allowed to use them, if they have the
necessary mechanism to do the right thing in the face of huge ring
latencies, bridges, and the rest of the evil in the world.
