Thanks Claire for your comment, the similar issue was discussed when burst gap loss was reviewed by IESG, to get
In line with the change to burst gap loss draft, I propose to add a similar sentence to say:
"
In this document, Jitter Buffer Metrics can only be measured over
definite intervals, and cannot be sampled.  Also, the value I=00
is reserved for future use.  Senders MUST NOT use the values I=00
  or I=01.  If a block is received with I=00 or I=01, the receiver
      MUST discard the block.
"
I believe this change addresses your comment.

Regards!
-Qin

Hi Dan,

Sorry for the late reply. I've reviewed this draft and think it is ready for submission to the IESG.

Just one small question.

Section 4.2 Interval Metric flag
It has defined the meaning of I=01,10 and 11. What would the receiver do if I=00?
I suggest to add following text:

The value I=00 is reserved, and MUST NOT be used.  If the
value I=00 is received, the XR block MUST be ignored by the
receiver.

Thanks and Regards,
Claire
