IMHO anything that is part of a packet on the network should be documented. Also if they are neccessary for understanding the algorithm, they should also be documented. And preferrably a specific code shouldn't change it's meaning over time; it's better to use a new code instead.
I'm not deeply in NTP at the moment, but felt to comment.
