Hi Mallory, Thanks for your review of the document.
Regarding your comment on the Transposition Scheme, there is no elaborate text on it in this document as that is orthogonal to the issues with RFC9252 addressed by this document - i.e., there is no issue with the transposition scheme as specified in RFC9252. Authors felt it would be easier to leave that part out and hence that paragraph in the introduction. That said, you have a point that a reader, who is not familiar, may find this harder to understand and hence we will add a reference pointer to the specific section 4 of RFC9252 on the first use of the term Transposition Scheme. This will reflect in the next document update. I hope this helps.
