Given the other thread I hesitate to mention, but Copilot says this:
With the “Integration With Stream Initiation” section removed, the document still references negotiation via XEP-0096 (see lines 96–97) and still defines an optional sid attribute in the jabber:iq:oob schema (line 219), but there is no longer any text defining what sid means or when it should be used. Consider either (a) removing sid from the schema, or (b) keeping it but explicitly documenting it as deprecated / for backward compatibility and clarifying the remaining XEP-0096 references accordingly.
That's a fair comment - I'm think it's suggested option (b) is the way to go for the schema, and maybe just remove the XEP-0096 references?
