As seen in the example, there is no notion about DataChannel internals. The only things negotiated here are the port on which the SCTP Stream runs and the name of the DataChannel. Further negotiation is happening through the &webrtc-protocol;, thus the DataChannel is identified through the content name.

For some uses like negotiated datachannels, it might be required to explicitly signal the channel properties. This is done by including a <channel/> element qualified by the 'urn:xmpp:jingle:transports:webrtc-datachannel:0' namespace &VNOTE; as child of the &TRANSPORT; for each channel that has to be signaled.
