Hi,

There's some text in draft-ietf-sidr-bgpsec-pki-profiles-10 sections 3.1 and 3.1.3 that I found confusing. For reference,

https://tools.ietf.org/html/draft-ietf-sidr-bgpsec-pki-profiles-10#section-3.1:

   This profile is also based on [RFC6487] and
   only the differences between this profile and the profile in
   [RFC6487] are listed.

https://tools.ietf.org/html/draft-ietf-sidr-bgpsec-pki-profiles-10#section-3.1.3:

The following X.509 V3 extensions MUST be present (or MUST be absent, if so stated) in a conforming BGPSEC Router Certificate, except where
   explicitly noted otherwise.  No other extensions are allowed in a
   conforming BGPSEC Router Certificate.

I checked with the authors, and the intent was that "the following" refers to all extensions in RFC6487 and the updates to extensions in draft-ietf-sidr-bgpsec-pki-profiles-10. However, I initially read the text in 3.1.3 as forbidding all extensions not mentioned in draft-ietf-sidr-bgpsec-pki-profiles-10, including some useful ones like the SKI.

I think it might be clearer to simply remove the entire first paragraph of section 3.1.3. RFC 6487 section 4.8 contains similar[0] text, and section 3.1 of the draft makes it clear that RFC 6487 section 4.8 applies.

[0] But not the same. That issue should probably be handled by draft-rhansen-sidr-rfc6487bis though.
