Thanks for taking over and making this a thing :)
No problem, and thanks for letting me use your work as a base :D
A few notes/nits,
- The jid attribute
Same as singpolyma, I would settle on requiring occupant-id I think
for all types of rooms, makes the whole thing simpler, and rooms
without it are scarce nowadays (at least in places that matter).
I also did include a note about this in implementation notes.
The feedback I've gotten thus far has made me realise that what I was
really going for here was a way to explicitly reference various things
(users, groups, rooms, etc), with the whole notification bit being an
addition. I guess if I were to do this from scratch, I'd want to
reframe the entire proposal around that, but I fear it might be a bit
late for that...
I went into more detail with my reply to singpolyma, but one of the
reasons I left in the ability to mention by JID is to allow you to
reference, not mention, other users, even in 1:1 chats and even if the
referenced user isn't present. In such a case, the goal is less the
notification, and more the ability to display a UI element (the pill),
which could be interacted with to provide buttons such as "Add contact"
and "Message user". For rooms, it could be "Go to room" or "Join
room".
The <noping /> element exists for similar reasons. If I were to reframe
the XEP from scratch, I suppose it would've made more sense to make
this the default, and then have a <ping /> or <notify /> element for
actually notifying the referenced user(s).
This seems to be a source of confusion; I've already updated my working
draft to try to clarify the goals I was going for more clearly, but
I can also just strip everything not directly meant to notify one
or more users out if no one else cares. Such things could go in a later
proposal, though I suspect the idea of referencing a user is largely
redundant with mentioning them...
Much to think about, but in any case, thank you for the feedback :D
Anonymous unique occupant identifiers for MUCs
(XEP-0421) [3] is
being used to mention in Multi-User Chat (XEP-0045) [1] instead of
a participant JID or a real JID. This allows us to have a common
solution across MUC, and also to use a stable identifier, that is
guaranteed to be unique per occupant (bare JID) and prevent
usurpation.
- The noping modifier
To me the purpose of the spec is to make mentions explicit. Thus
changing the status-quo and making the non-usage of this spec "not" a
mention, which would make the modifier redundant and confusing
(mentioning not to mention).
This somewhat conflicts with implementation notes:
Implementations SHOULD also allow sending
participants to talk
about someone without having to mention them.
Might be useful as a temporary measure but I certainly wouldn't want
that to stick around.
