Hello,
I’d like to know how this would interact with the change proposed by Dimitris for the VATEL thing.
In my case I did put on hold my own proposed change (regulation of use of QGIS for organization validation) until the doc was in RFC format, and I wonder if we should do the same for other proposed changes, as I guess the order of the ballots is important here.
Best,
Pedro

You have to try to interpret what phrases like “are strongly advised to adhere”, which isn’t even a RFC 2119 SHOULD. And it can’t even be a SHOULD, because as an informational RFC, it is prohibited from having requirements, even SHOULDs! That’s why it’s written that way. Also, informational RFCs are not examined as closely for inconsistencies (because there are no requirements!) which is how divergences like section 4 vs 6 happen. It wasn’t intended to be used as a compliance document.

What we need to be discussing is what’s best for us, not RFC 3647 requires, because RFC 3647 has infinite leeway. As Aaron and I have been pointing out, you’ll find lots of divergences at level three, and there’s even lots of additional content in level two, just because a lot of newer content doesn’t really have a good fit in RFC 3647.

I just don’t want people overstating what the rules actually are, because a lot of people’s time has been wasted enforcing RFC 3647 in a way that is far stricter than was ever intended (one of the reasons I’m so vocal on this issue is because I got this point of view from one of the original authors).

While it is true that compliance with a Normative RFC is voluntary, if you do choose to comply, the RFC has requirements stated in RFC 2119 standards language that make it clear what the compliance rules are. Informative RFCs like 3647 do not have any normative requirements at all. They merely contain information.

There is no RFC 3647 section 4.3.2.1, which proves my point. RFC 3647 only has a two level outline structure.

The outline contains a specific section labeled as "3.2.1 Method to prove possession of private key". That means we cannot re-use the number 3.2.1 for something else.

This means that it contains no requirements and it’s impossible to be out of compliance with it. This is why I put quotes around “compliance”. Any requirements around it need to come from elsewhere, for example, a root program requirement that requires a particular document to be in RFC 3647 format. But that’s vague and informal, because 3647 doesn’t have requirements, it just has an outline and suggested contents. It’s not 100% precise what “MUST be in RFC 3647 format” means, and we need to just acknowledge that (specifying it precisely would be a colossal waste of time).
>
> So what does “RFC 3647 format” mean? RFC 3647’s outline only covers the first two levels. So “Section 3.2: Initial Identity Validation” is a RFC 3647 section header, and most reasonable interpretations of “RFC 3647 format” would require it to exist with that or a substantially similar name and contents.
>
> Section 3.2.1, on the other hand, is not an RFC 3647 section. It’s common to have a third level of headers that mirror the “bullet points” in the suggested content for the section, but those are just unordered bullet lists in RFC 3647. Claiming that section 3.2.1 of a document in RFC 3647 must describe private key protection goes beyond what RFC 3647 says. Section 3.2 just “contains the following elements”, so private key protection is just one of several topics that one might discuss in section 3.2. It could be section 3.2.1, but it could be elsewhere in 3.2, and it’s perfectly fine for 3.2.1 to not exist, have different content, etc.
>
> Figuring out where section 11.1 goes is not trivial, but at first glance, section 3.2 is not an unreasonable choice, and I can understand why Inigo made it. And there isn’t a compliance reason why it can’t be section 3.2.1, if that’s what we want.
>
> Of course, we could convert the recommended bulleted sections to a numbered list of subsections (we often do elsewhere), in which case section 3.2.1 could be “Private Key Protection” with contents “No Stipulation”. If we do that, I suggest we follow the rest of the bullets as well.

> I think that strictly speaking, in RFC 3647 this section is the 4.3.2 Initial Identity Validation and the first bullet is about proving the possession of the private key, but there´s no specific section other than the general approach that we´ve implemented.
> That said, the current EVG does not include anything about the possession of the private key because that´s covered in the TLS BRs so that section does not exist in the EVGs and therefore I didn´t know how to avoid/implement it.
> I decided to continue with the normal numbering for an easy checking, so all 11 section is moved into section 3.2 and the rest of the sub-numbers do not change (so 11.1 would be 3.2.1, 11.1.1 would be 3.2.1.1, etc.)
> I understand your point but I think we can´t create a section 3.2.1 for private key possession because there´s no such a text in the EVGs (and don´t think we should add anything new, even a NA for that) and don´t know which other sections we can create under 3.2 that can break the current equivalence, which again was done for an easy comparison.

This particular section is labeled "Method to prove possession of private key" in RFC 3647 so I don't think it is appropriate. I think it's best to create new subsections under 3.2.
