Hello,

i've been selected for an OPS-DIR review of the draft.

The draft is very simple and straightforward and ready to be moved to next stage. I've some very minor nits/suggestions.

-Abstract: i suggest rewording, it's a bit hard to follow. Maybe something like: This document revises the process used by the RPKI to manage the revocation of CRL extensions. I'm not an English native speaker and this can be further improved.
- Introduction: i like the way it's arranged. All draft should say what is the context, what is the problem that the draft aims to solve and how it will do it.
- 2.Summary: I don't think a summary is needed at the beginning. This is part of what the draft aims to do, i would put this text in the intro.
- i would also merge 1.3 and 3. It's all about the changes to RFC6487. Maybe you could have 3.1 with the summary of the changes and 3.2 with the updates section by section.

From and pure operational point of view i don't see any issue introduced by the draft, and this is also correctly stated in section 4.

Thanks 
Daniele
