-"previous" IDs. They are intended to be non-persistent data such as user
-presence, typing notifications, etc.
+Some EDUs may lack a room_id, while others, such as typing notifications, 
+include a single room_id, and some, like read receipt EDUs, can have 
+multiple room_ids.. They are intended to be non-persistent data such as
+user presence, typing notifications, etc.
