Strictly speaking, you are correct, in that if one interprets SHOULD/MAY as 'not bother', one does not need to check, unless the presence of the remote end doing the feature results in your barfing. However, if one interprets SHOULD/MAY as 'bother', then one most likely needs to check on the capabilities of the far end or handle the varying data elements or protocol states that will or will not happen. SHOULD/MAY is used for many other cases than whether to implement a protocol feature that changes how the protocol works as viewed by its peer. Keith |
