I'm fine with not having those flows explained in the next version of the XEP. However, are we going to explain that tokens need to be validated and that more flows with other Oauth servers will be needed? My knowledge of OAuth went from 0% to 1% in the last weeks so I guess that adding some basic explanation of how things work is going to be useful for implementors that are no OAuth expert.

Yes, I'll add that use case in the next version of XEP-0235, but I think
it's tangential to what Sylvain is talking about, because you could use
the IQ exchange with a pubsub service, a MUC service, an IM server, or a
standalone OAuth service that's used by all of the above. However I have
no objections to standalone OAuth services, it's just that we'd need to
define the interactions between said service and all the other services
that might be deployed in a domain (e.g., how does the pubsub service
check an OAuth token with the OAuth service). Those flows won't be in
the next version of XEP-0235 but they might be in a future version, or
in a future spec that builds on XEP-0235.
