Hi Diego, Joe, all,

Thank you for confirming that these changes are OK.

BTW, we received an offline comment about how the flow part is supposed to 
work. This is a good comment that is worth clarified in the text. Added this 
NEW:

6.2.  Anchoring Flow Structure

   The characterization of a flow depends on the underlying data model
   that adheres to the IM.  From that standpoint, the IM does not make
   an assumption about flow characterization and identification.  Future
   flow-oriented data models MUST ensure that the flow structure is
   anchored so that the discards are unambiguously associated with a
   flow.
Also made some other changes through the document to make the intent clearer, 
fix nits, etc. See: 
https://o-pylypenko.github.io/draft-ietf-opsawg-discardmodel/draft-ietf-opsawg-discardmodel.txt.

Cheers,
Med (as author)

Hi Joe/Diego,

Thank you for catching those.

The rendered diff can be seen at: 
https://author-tools.ietf.org/api/iddiff?url_1=https://o-pylypenko.github.io/draft-ietf-opsawg-discardmodel/draft-ietf-opsawg-discardmodel.txt&url_2=https://o-pylypenko.github.io/draft-ietf-opsawg-discardmodel/shephred-review/draft-ietf-opsawg-discardmodel.txt

The PR is available at: 
https://github.com/o-pylypenko/draft-ietf-opsawg-discardmodel/pull/62, fwiw.

@Diego, the warnings about "weird spacing" is a false positive (that is used in 
tree diagrams).

Please let is know if any further change is needed.

Cheers,
Med (as author)

Dropping chairs and re-adding the list.

Thanks, Diego!  I read the write-up, and I think there should be a new I-D 
before it goes to the IESG (reference: 
https://datatracker.ietf.org/doc/draft-ietf-opsawg-discardmodel/shepherdwriteup/)

Specially, I agree with you that the RED95 reference is incomplete.  On the 
YANG module, there are a few issues.

I don't think nacm:default-deny-all belongs at line 180 of 
[email protected]<mailto:[email protected]>
 since this is the statistics container itself.  Moreover, I think this 
augmentation should be to /if:interfaces/if:interface/if:statistics since 
if:interfaces-state is deprecated (or maybe do both?).  Finally, the YANG 
module's revision date is different than the extraction date.

Joe

I do not know what it might happen, as the message I have in my "Sent" folder 
does have the attachment...

Anyway, I have just uploaded the writeup to the URL Med pointed.

Be goode,
