That was one of my initial complaints ... > If this sentense misleads readers to think that users can choose all > conbinations, I will rewrite it as: > "... The choices of Key Size are defined as following which are > compatible with [RFC3686]." ... and that's essentially what I had proposed for that paragraph. And yes, since that's written in the overview of Section 2, which lays out the skeleton of the remainder of the section, the immediate consequence of this change should be to drop sections 2.2 and 2.3 as well, as explained in my original review. (To recall: The argument presented there was that, after dropping inappropriate text, the remaining text in 2.2 & 2.3 would be a simple -- yet verbose -- restatement of the first paragraph of Section 2, and hence redundant anyway.) Bingo! We are converging.
