First: Data channel label uniqeuness
19:19:32 [stefanh]
prop: update the spec to say do not have to be unique

I suggest to add a note specifying "Multiple channels may contain same label".


add a line after explanation

The RTCDataChannel.label attribute represents a label that can be used to distinguish this RTCDataChannel object from other RTCDataChannel objects. The attribute MUST return the value to which it was set when the RTCDataChannel object was created.
 "JS applications are allowed to create multiple channels with same label"
