COMMENT:
----------------------------------------------------------------------

(Note that there was a post IETF LC IPR declaration. We should discuss
whether we need to re-run the last call. I think Alissa is on top of
this, so I did not make this a DISCUSS)

Otherwise, I have a few minor comments:

- 4: "The report block MUST be sent in conjunction with the information
from the Measurement Information Block [RFC6776]. "

"MUST be sent in conjunction" is ambiguous. I think you mean that, if the
LC block is sent, the Measurement Information Block MUST also be sent.

=== Editorial===
- 1, 2nd paragraph:
Please expand QoE on first mention.
Also, I think there's a cut-paste or edit error in the last sentence:
OLD:
     Evaluating error concealment is important in the circumstance in
estimating the subjective impact of impairments.
NEW:
     Evaluating error concealment is important for estimating the
subjective impact of impairments.

-4:, 1st paragraph:
There are several instances of "this metric block" where the antecedent
for "this" is not clear. I think they all refer to the loss concealment
block. I suggest changing most or all instances of "this metric block" to
"the loss concealment block."
