Hi all!
MUST a pubsub service advertise <feature var='
http://jabber.org/protocol/pubsub'/> with service discovery 'info'
responses?
XEP-0060 shows this being done in examples 8 and 18, but there is no
normative text that defines this.
The feature is not listed in its "Feature Summary" section, and is not
registered with the Registrar.
There has been a discussion around this in the XSF's Discussion chat room
today (logs here:
https://logs.xmpp.org/xsf/2025-10-03#2025-10-03-f173fd843da7c3ee ).
There are implementations in the wild that require that feature to be
advertised, while other software doesn't advertise it.
Given the conflicting implementations, I believe that it would be good to
have normative text be added to XEP-0060 to clarify things. I'm not sure
yet what that text should be.
What do you think?
Kind regards,
Guus
