Suggestion from Bas:   Make explicit in the spec that when using websockets the unsubscription will simply remove the websocket endpoint. What will happen with the websocket disconnected? I assume that it will remain and can reconnect. Another approach would be to re-subscribe and treat the disconnect as an unsubscribe. This approach has the elegance that there will be no dangling websockets. What do you think?   Pursuasive: Add clarification that when unsubscribing a websocket subscription, the websocket will be destroyed. A new subscription will receive a new websocket connection, the old one will not be used.
