RE: New Version Notification for draft-mcmanus-httpbis-h2-websockets-02.txt

Hi Patrick,

This proposal is interesting. One small point, the introduction says:

This tunneled stream will be multiplexed with other regular streams
on the connection and enjoys the normal priority, cancellation, and
flow control features of HTTP/2.

On the surface this sounds sensible, however I think there could be some issues with clients that naively place dependencies on the completion of a WebSocket stream. This assumes that the WebSocket stream is longer lived than the typical request/response stream. Funnies with priority may also surface from pushed streams that are anchored of off the WebSocket stream (is it even possible to push HTTP resources on a WebSocket parent?)

Kind regards
Lucas
