I think that Ale's expression that he had difficulty understanding the
description of the tree walk as written is a strong sign we still need to
improve the language. Of the people involved in this specific
discussion, as far as I know, he's the only one who's first language
isn't English. That's true for most of the people in the world, so I
don't think we can call it quite done.
I took a look at the description ot the tree walk in section 4.6 and I
didn't see anything to change. I suppose we could add a sentence at the
top of the section reiterating some of the discussion in 4.4 that you do
tree walks on two domains to see if they are in relaxed alignment, or that
you do a tree walk on the RFC5322.From domain to find its policy domain,
but those seem marginal.
What Ale seemed to be asking for was something saying these aren't zone
cuts and it's not the PSL. I don't think that would be a good idea. The
list of things we are not doing is unlimited, and mentioning some of them
just leads to questions about if you're not doing them, why did you mention
them?
I might have messed up that introductory paragraph several times, but
that's not the main point. *Section 4.8* mixes the definitions of
Organizational Domain and relaxed alignment. That way, it is difficult to
guess which precondition applies to which definition. I think native
English speakers may misunderstand it too.
In particular, the condition that a tree walk must have met a DMARC record
to be eligible for org domain determination —that is, org domain cannot be
determined unless a DMARC record is found— is not evident. It is expressed
only implicitly at the beginning. Then the paragraph "To discover the
Organizational Domain for a domain, [...]" can be interpreted as the start
of the org domain discovery algorithm definition, in the middle of the
alignment discussion, dropping the preconditions stated for alignment.
The juice of my proposal is to define the org domain discovery algorithm in
its own section, and discuss relaxed alignment elsewhere.

Ale
