# Éric Vyncke INT AD comments for draft-ietf-netmod-yang-semver-26
CC @evyncke

Thank you for the work put into this document.

Please find below some blocking DISCUSS points (easy to address), some
non-blocking COMMENT points/nits (replies would be appreciated even if only for
my own education).

Special thanks to Lou Berger for the shepherd's detailed write-up including the
WG consensus and the justification of the intended status and the large number
of authors.

I hope that this review helps to improve the document,

Regards,

-éric

## DISCUSS (blocking)

As noted in
https://datatracker.ietf.org/doc/statement-iesg-handling-ballot-positions-20220121/,
a DISCUSS ballot is a request to have a discussion on the points below; I
really think that the document would be improved with a change here, but can be
convinced otherwise.

### Section 4.5

In rule #1, the first "SHOULD" has a "unless", but why is the 2nd one not a
"MUST" in `in which case the artifact version "X.Y.Z+1_non_compatible" SHOULD
be used instead` ?

I am unable to fully understand the rule #2.i `unless that version has already
been used for this artifact but with different content, when the artifact
version SHOULD be updated ` (which also has a SHOULD without the required IESG
guidance per
https://datatracker.ietf.org/doc/statement-iesg-statement-on-clarifying-the-use-of-bcp-14-key-words/
) The part that I do not understand is the use of "when" in the sentence.

There are also too many "SHOULD" without any guidance, i.e., why not using
"MUST" then ?

### Section 6

Why not a "MUST" in `SHOULD begin with a 0` ?

## COMMENTS (non-blocking)

### Section 4.5

`The following four rules specify` is actually followed by 5 rules ;-)

### Section 4.6

Suggest to add a graphical representation (e.g., the trees used in the 
beginning of this I-D).
