Na, the standardization process starts much earlier. Using the example of the IETF process, after which XMPP standardization process is largely modeled: standardization starts when you submit an I-D to IETF and/or approach an IETF WG.

> What matters is what the standard itself looks like, do you have a coherent specification which specifies the current way of doing things, including optional components? Or do you have a set of independent ways of doing it, because the standardization process doesn't actually decide what is the correct way of doing something (e.g. managing a group chat)

Well put and I totally agree (I think no one would have a reason to disagree with that statement).
