I'm currently working on OMEMO implementation in Salut à Toi thanks to the
work of Syndace (https://github.com/Syndace/python-omemo), and I have two
issues with it:
- SàT is using xml:lang attribute, and I don't see a way to specify it with
OMEMO, how should I do? What are business rules when several bodies are
available (I know it's not common, but it's allowed by RFCs)?
- only the first item of PEP nodes are used, and it seems that client are
implicitly expecting max_items=1 (i.e. singleton pattern), but I don't see
any mention of that in the XEP. Furthermore, max_items support is optional
in Pubsub, and I see in my PEP nodes the same items published several
times. This could be mitigated by using a well known id for the item (e.g.
the OMEMO namespace), so even pubsub services not featuring max_items would
simply override the existing item.
That's all for now, thanks
