On TD26 - Fast TCS and M/S negotiation in H.323v4

Thanks for the writeup on earlyH245Control.  I would like
to suggest that make acceptance of fastStart independent
of the acceptance of earlyH245Control.  It might be useful
for the called endpoint (or gatekeeper) to accept early
H.245 and proceed with TCS and M/S negotiations before
it establishes any media channel via the FastStart procedures.
This could be done by permitting the earlyH245Control element
in all messages (like fastStart), or in the basic H323-UU-PDU
(like h245Control).  That way, FastStart is accepted by the
return of a fastStart element, and acceptance of early H.245 is
clearly accepted by the return of an earlyH245Control element.
The use of the earlyH245Control tunnel would then be enabled.
(Is there any reason to move to the h245Control tunnel?)
Should we prohibit both an earlyH245Control and an h245Control
element in the same message?  What do you think?
