Hallo, XEP-0022 Message Events has been obsoleted and says:
Note: More modern protocol extensions for this functionality have been defined in Chat State Notifications (XEP-0085) [1] for the composing and offline events and in Message Delivery Receipts (XEP-0184) [2] for the delivered and displayed events; those specifications supersede this one. However, I don’t see how XEP-0085 works for the offline event, which is described as "Indicates that the message has been stored offline by the intended recipient's server“. Is this case maybe covered by XEP-0079 instead? (I am not sure about it) Similarly the Displayed event isn’t really handled by XEP-0184 because it's only about delivery. XEP-0333 might be the more appropriate XEP for the Displayed event. Hence I think the „Note“ from XEP-0022 is partially wrong and misleading and I want to propose to update it to the correct successor XEPs. - Christian
