* While the specification states:

* "This event type is used when sending encrypted events.
* It can be used either within a room
* (in which case it will have all of the Room Event fields),
* or as a to-device event."
* "The encrypted payload can contain any message event."
* https://matrix.org/docs/spec/client_server/latest#id493
*
* -- for most of the cases the message event is the room message event.
* And even for the to-device events the context is for the room.
*
* So, to simplify integration to the timeline, EncryptedEvent is a RoomEvent
* inheritor. Strictly speaking though, it's not always a RoomEvent, but an Event
* in general. It's possible, because RoomEvent interface is similar to Event's
* one and doesn't add new restrictions, just provides additional features.
