Why is XEP-0386 (BIND2) talking about <authorization-identity/> at [1] whereas
XEP-0388 (SASL2) is talking about <authorization-identifier/> at [2]?
Bot specs use it for exactly the same thing: communicating the bare or full
jid (if a bind occured). Why this double-element? XEP-0388 even states
> If the Client is now authenticated, the Server sends a <success/> element,
which contains an <authorization-identifier/> element containing the negotiated
identity - this is a bare JID, unless resource binding has occurred, in which
case it is a full JID.
So it seems like a perfect fit to communicate the full jid after bind using the
SASL2 element, why was this extra BIND2 element added?

Greetings.
This is a concern about backward compatibility.
Preface
-------
Earlier, this evening, after I have sent a series of corrections to
messages at the group chat of XSF Discussion, Mr. Guus has mentioned
the concern of backward compatibility with clients that do not support
message corrections, or reactions and other features that have a visual
impact.
Wed 10 Dec 2025 06:21:44 PM - Guus:
> My client displays a wall of text in this chat room, full of quote
> chains, reactions, links, and corrections.
>
> It's completely unreadable. I'm using a very old client with a basic
> interface, but until recently, this was never an issue.
>
> It's disappointing to see that modern XMPP usage can make my
> experience so abysmal - at least in rooms where newer clients are
> active (even if _or perhaps because_ they try to implement "backwards
> compatibility" features).

Concern
-------
I was wondering whether some features, which have visual impact on
messages, should have XML Namespaces (xmlns).
Consideration
-------------
This would mean that messages that are marked as "corrected messages"
will not be displayed with clients that do not support message
correction, due to a namespace which is not recognized by clients that
do not support that feature.
Kind regards,
Schimon
Version 1.35.3 of XEP-0045 (Multi-User Chat) has been released.
Abstract:
This specification defines an XMPP protocol extension for multi-user
text chat, whereby multiple XMPP users can exchange messages in the
context of a room or channel, similar to Internet Relay Chat (IRC). In
addition to standard chatroom features such as room topics and
invitations, the protocol defines a strong room control model,
including the ability to kick and ban users, to name room moderators
and administrators, to require membership or passwords in order to
join the room, etc.
Changelog:
* muc#roomconfig_allowinvites doesn't restrict owners but enables
additional permissions for members. (spw)

This specification describes how to implement XMPP-based discussion
forums.

Version 1.0.0 of XEP-0440 (SASL Channel-Binding Type Capability) has
been released.
Abstract:
This specification allows servers to annouce their supported SASL
channel-binding types to clients.
Changelog:
* Accept as Stable as per Council Vote from 2025-11-18 (XEP Editor
(dg))

The XMPP Extensions Editor has received a proposal for a new XEP.
Title: Initial Authentication Pipelining
Abstract:
This specification defines a protocol for discovering if the SASL2
<authenticate> can be pipelined safely along with the stream open, and
if so allows the client to perform this pipelining safely.
URL: https://xmpp.org/extensions/inbox/iap.html
The Council will decide in the next two weeks whether to accept this
proposal as an official XEP.
Version 0.7.0 of XEP-0353 (Jingle Message Initiation) has been
released.
Abstract:
This specification provides a way for the initiator of a Jingle
session to propose sending an invitation in an XMPP message stanza,
thus taking advantage of message delivery semantics instead of sending
IQ stanzas to all of the responder's online resources or choosing a
particular online resource.
Changelog:
* Remove local redefinition of jingle <reason/> element in XML schema
and reference existing.
* Make usage of <reason/> element optional in schema, as specified in
the text.
* Add missing definition of 'empty' type in XML schema. (lnj)

Hi everybody,
On ActivityPub (AP) there is currently a thread discussing polls:
https://mastodon.social/@Lautaro_Ferrero/115625081357268012
(it switches to English after few messages), and I think that it's good to
bring that to standard@ to discuss that mater.
We can probably all agree that a poll specification would be a good addition to
XMPP, but it's not as trivial as it may first appear to do it well. In my
opinion we have the following requirements:
- Must work in group chat, notably in MUC including anonymous room and with
e2e encryption
- Must be flexible enough to enable gateways to poll on other protocols. I
notably intend to make a compatibility layer with ActivityPub in the gateway
I'm working on
- Must be used for many use cases, from voting for lunch location, selecting a
date for an event, to various opinion polls (or to vote on XMPP membership ;)
)
- Must support constraints: one vote per JID, vote on single or multi items,
vote public or hidden, result showed in real-time or only after the end of the
poll, etc.
I've been thinking about polls for a while, and my idea was to use a
combination of data form with XEP-0346 (Form Discovery and Publishing) for
public polls and ad-hoc service for complicated constraints.
On AP, Larma raise the very valid concern that we can't use IQ with anonymous
MUC, which exclude ad-hoc or pubsub. He suggested a direct message approach.
We probably need an hybrid approach, with 2 to 3 variant:
- direct message approach, necessary for anonymous MUC
- pubsub based one, probably using XEP-0346, having a service has many
advantages, and pubsub is already present in most servers.
- maybe an ad-hoc approach for complex use cases, something based on XEP-0050
(Ad-Hoc Commands) seems adapted.
John Livingston has already work on this on Prosody for Peertube, using a
dedicated <x-poll> element, you can check it at:
https://livingston.frama.io/peertube-plugin-livechat/technical/polls/
index.html
I'm volunteering to write a protoXEP for that, with John Livingston if he's OK
with that, and anybody else interested.
I'm looking forward for your though on the mater. This can also be discussed
at the summit next month.
Best,
Goffi
