Hmm, I talked to <person involved in the process> earlier this year to let him 
know that 0x10 was already being used, I'd assumed it'd be marked as RFU, but 
I guess not.  Maybe we could use 36, which follows on from the SessionTicket 
one at 35 and is far enough up that it won't be overrun for awhile.

Annoying though, there are already deployed implementations that use 0x10.

Peter.
