Note: OMEMO encrypted group chats are currently specified to work with &xep0045;. This XEP might be updated in the future to also specify the usage in &xep0369;.
+A Multi-User Chat room that supports OMEMO MUST be configured non-anonymous and SHOULD be configured members-only.
+A participant wanting to send a message to a group chat MUST first retrieve the members list and then fetch the device list for each member (via pubsub and to their real JIDs) and then subsequently fetch all active bundles.
+On join a participant MUST request the member list, the admin list and the owner list as described in XEP-0045 §9.5, XEP-0045 §10.8, and XEP-0045 §10.5 respectively. Those three lists MUST be combined as the recipients of OMEMO encrypted messages. Once joined a participant MUST keep track of affiliation changes that occur in the room. This is both for removals (users getting banned or have their affiliation set to none) and users becoming members, admins or owners.
+Before sending a message a participant SHOULD explicitly fetch device lists for all other participant if the list isn’t already cached..
+Before publishing a freshly generated Device ID for the first time, a device MUST check whether that Device ID already exists, and if so, generate a new one.
