Sorry for not seeing your earlier response (and for not spotting the
change in the diff correctly).
Yes, this change is sufficient to address my comments.

Hi Robert,
I believe I have responded you in February, if you check the mail archive of
xrblock.
Follows was my response before. And I uploaded a new version to reflect that
since I didn't get your further email. Sorry for assuming that you received my
response.

Hi Robert,
Thanks for the comment.
I propose to change the last paragraph of 5.2.2 from
"
The following metrics can also be considered for WebRTC's Statistics
API: number of discarded key frames, number of lost key frames,
number of discarded derived frames, number of lost derived frames.
These metrics can be used to calculate Media Loss Rate (MLR) of MDI.
Details of the definition of these metrics are described in
[RFC7003]. Additionally, the metric provides the rendered frame
rate, an important parameter for quality estimation.

The metrics in this category includes
: number of discarded key frames, number of lost key frames,
number of discarded derived frames, number of lost derived frames.

This change is to just talk about the metrics itself, so as to avoid any
confusion that readers may have. The fact is that the W3C has already included
the metrics, and made an informational reference to this document.
If the proposal looks good to you, we'll reflect it in the new version.

Summary: Ready for publication as an Informational RFC, but with nits to
consider before publication
Note that this is identical to my last call review, which I don't think I've
seen a response to.
The document argues to include things in the W3C statistics API in the last
paragraph of 5.2.2. Section 7 seems to say those have been included already. It
would be good to rework both of these mentions to reflect what's true at the
time of the publication of the RFC, in a way that the text will make sense when
read years from now.
