Another way to address this (if the request and response Id is one octet long) the request using the first 7 bits (form 0.. bit 6) and use bit 7 only for response... I mean set the most significant bit 1 when is a response ID....

Bad example:

request: 0x00
response 0x80

This expands the number of request and response to use. Also, same criteria applies to a 16bit request/response ID.

P.S. Also, this is just a thought..

One usual way of handling this is to split the code space in half, i.e. using 0 
to 127 for requests and 128 to 255 for response statuses.  Obviously, we don't 
need request codes yet -- but maybe we can use the opportunity to get rid of 
the strange language about using the size of the message to distinguish 
different kinds of requests.

Just a thought (and no WG chair hats involved).
