Hi.
I had a look at the revised diff. Looks pretty good now.
Couple of minor points in line below.
Cheers,
Elwyn

Fixed.
s5.2, Event ID:
An event can be a Client authenticating with the Agent, a Client to
Agent operation, or a Client disconnecting from an Agent.
This is a good thing, but I am not sure that the format provides a way
to identify the authentication and disconnection events.
The intent was that these would be Operations (i.e., AUTHENTICATE
CLIENT, DISCONNECT CLIENT). There is nothing in the text that
precludes this. We can explicitly state this.
I think stating it explicitly would be a good idea.
s5.2, Starting Timestamp:
[I don't understand 'three points of prevision'.] Maybe...
OLD:
Given that many I2RS operations can occur in rapid succession, the use
of fractional seconds MUST be used to provide adequate granularity.
Fractional seconds SHOULD be expressed with at least three points of
prevision in second.microsecond format.
NEW:
Given that many I2RS operations can occur in rapid succession, the
fractional seconds element of the timestamp MUST be used to provide
adequate granularity. Fractional seconds SHOULD be expressed with at
least three [or more?] significant digits in second.microsecond format.
END
Changed.
Do you think millisecond resolution will be good enough? I put in three
because of the 'three points of prevision' but wonder if you might
need something closer to microsecond resolution in high throughput
routers? I don't know what might be desirable - I have some experience
of a similar logging system (DTN2) and full microsecond resolution is
occasionally useful.
s5.2, Ending Timestamp:
See the comments on the Starting Timestamp - though I think you could
just refer to the words in the Starting Timestamp and avoid duplication.
Done.
s7.4/s7.4.3: Given that the I2RS pub-sub access method is
mandatory-to-implement, i think I-D.ietf-i2rs-pub-sub-requirements has
to be a Normative Reference.
Changed.

Thanks again for the review!
Joe
