Hey everyone,
I am a bit confused/worried about section 5 (Requirements for IPv6
support in software). There is a list, of what a developer/vendor MUST
(at a minimum) support.
However, the list contains multiple bullet points that include words
that make them seem optional (like "something SHOULD be supported" or
"it's recommended").
I don't have any experience with the creation of RFC and just joined
this mailing list to be able to see what you are doing here out of
interest, so I think this might be (at least partly) intended, as some
of these bullet points seem to have been copied from other sources
(e.g., https://www.ripe.net/publications/docs/ripe-554 contains this
first bullet point with "recommended").
However, I think the standard should make sense on its own and therefore
don't think that this is a valid justification. Things should be clearly
marked as either mandatory or optional.
Therefore, I would suggest rephrasing the introduction sentence from
Software developer/vendor must at a minimum do the following things
to guarantee this:
to
[A] software developer/vendor should at a minimum do the following
things to guarantee this:
However, in case some things in the list should be mandatory and some
optional, I think it might make even more sense to split the list in an
optional and a mandatory list.
If all the things in the list are actually mandatory, I would propose
the following changes to the bullet points:
From
It is strongly recommended not to use any address literals in
software code, as described in “Default Address Selection for Internet
Protocol version 6” [RFC6724]
to
Address literals must not be used in software code, as described in
“Default Address Selection for Internet Protocol version 6” [RFC6724]
From
Every place where IPv6 addresses are shown or output the notation as
specified in "A Recommendation for IPv6 Address Text Representation
[RFC5952]" should be followed
to
Every place where IPv6 addresses are shown or output[,] the notation
as specified in "A Recommendation for IPv6 Address Text Representation
[RFC5952]" must be followed
From
When setting up a connection the software should follow Default
Address Selection for Internet Protocol Version 6 [RFC6724] or Happy
Eyeballs Version 2: Better Connectivity Using Concurrency [RFC8305]
to
When setting up a connection[,] the software must follow Default
Address Selection for Internet Protocol Version 6 [RFC6724] or Happy
Eyeballs Version 2: Better Connectivity Using Concurrency [RFC8305]
From
These requirements should also be checked in any library or tools
used by the software
to

I'm not particular interested in what wording exactly is used, these are
just some suggestions.
Please feel free to let me know what you think.
