Hi Colin,

Apologies for the delay, my proposal is the following:


   In this document, we provide rationale for choosing additional RTP
   metrics for the WebRTC getStats() API [W3C.WD-webrtc-20150210].  The
   document also creates a registry containing identifiers from the
   metrics reported in the RTCP Sender, Receiver, and Extended Reports.
   All identifiers proposed in this document are RECOMMENDED to be
   implemented by an endpoint.  An endpoint MAY choose not to expose an
   identifier if it does not implement the corresponding RTCP Report.
