Description

Comment on draft-jesup-rtcweb-data-protocol:

All DATA_CHANNEL_OPEN messages MUST be sent reliably and in-order.

[BA] The DATA_CHANNEL_OPEN message is not acknowledged at the application layer. Therefore all that reliability and in-order delivery provides (within the SCTP implementation) is the message was *received*, which doesn't tell you if the message was acted on or not. If you do support app-layer acknowledgement to address this, then you don't need transport reliability.
