Re: [xrblock] I-D Action: draft-ietf-xrblock-rtcweb-rtcp-xr-metrics-03.txt

Hi all,

I updated the reference link and made the following recommendation
(based on the issue raised by Colin Perkins):

   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.


I believe the document ought to make a stronger recommendation than OPTIONAL.
The document does provide enough rationale for implementing the additional
metrics.

Although, in the end I went with "SHOULD implement if the
corresponding XRBLOCK is implemented."

Feedback on the above proposal is much appreciated.

Cheers,
Varun
