I agree with Acee, would like to see the example he mentions removed in case people try to copy it. But otherwise I am happy to see this document published.

Hi Kent, Mahesh, et al,

I have read the draft and support publication. I have two comments on
-14 version.

1. The tree diagrams do not fit within the draft pages. Note that
versions of pyang support the —tree-line-length parameter and this may

I used the —tree-line-length=72 as the parameter to generate the tree,
and that is why you see the line wrap around.

I guess then you need to manually format it so it fits.

2. While it is non-normative, I’d prefer to have appendix A.1 removed.
It was a mistake for vendors to mix packet filtering and route filtering
in the first place and the draft should not insinuate that the model
be augmented to do this.

The example is just an example of how the model can be extended. There is
no implication that the model will be augmented to support mixing of
packet filtering with route filtering.

I understand that. However, it is more an example of how it should not be
used. Do you really want to publish this?
