Still have many questions to the XEP. It's needed to add some examples of notifications to be sent:
1. How to determine that the notification is from the past and not the current notification? 2. Will the server send retracts or node configuration changes notifications from the past? Possibly, this "ago" payload should be included in presence automatically by server since it's not always possible to determine the value on the client side (I already gave an example when other resource is becoming online with higher priority and then other resources can't receive events in case of pubsub and not presence subscription). Another still uncovered thing is how to determine missed notifications in the case of connection failures.
