Shepherd writeup

I'd like to request that draft-ietf-xrblock-rtcp-xr-bytes-discarded-metric-01,
"RTP Control Protocol (RTCP) Extended Report (XR) for Bytes Discarded
Metric", be published as a Standard Track RFC.

I have reviewed the draft in detail and XRBLOCK working
group was given plenty of opportunity to comment through
several WGLCs.

The contents of this document previously belonged to
draft-ietf-xrblock-xr-discard-rle-metrics [RFC7097]. Towards the end
of the IESG review, a point was made that during PM-DIR review,
Alan Clark raised a point that the two metrics that were originally covered
in RFC7097 should indeed be in a separate document. So that
implementers are not bound to implement two different metrics to
claim compliance to the RFC.

After a discussion at the IETF87, the WG decided to take out the text
regarding discarded-metric for the benefit of implementers into a
separate draft which is the draft mentioned in this publication request.

The contents of this document hasn't been changed in any technical
form since it was separated from RFC7097, this was confirmed by
few WG members during the WGLC and by me.
