Hi Andrzej and list,
I re-read the git history of MIX and decided that the jid attribute in
the examples of MIX-PAM is probably a remnant from 2018. Back then the
"Proxy Jid" attribute was replaced by the concept of Stable Participant
IDs in MIX-CORE.
I created https://github.com/xsf/xeps/pull/919 that changes the examples
of MIX-PAM accordingly.
