[hybi] Multiplexing - closing a logical channel

[Zhong Yu <[e-mail]>]

Hi,

A vanilla WebSocket connection can be half-closed, i.e.

    X sends a close frame to Y,
    then continues to read frames from Y.

    Y receives a close frame from X,
    but continues to send data frames to X.

However the multiplexing draft seems to require that a logical channel
cannot do that - a logical channel is either active or inactive, as
soon as it becomes inactive, by sending or receiving DropChannel, the
channel cannot be used further, on either direction.

If my understanding is correct, then I wonder what's the reason for
this behavior? Why don't we allow close frames exchanged on a logical
channel so that the closing process of a logical channel is consistent
with that of a vanilla WebSocket connection?

Thanks,
Zhong Yu
