I have performed a review of this draft as assigned by the DNS Directorate, andw these reviews are intended to pay close attention to aspects of the draft that intersect with the DNS and its operation. From this perspective, there is no material in this draft that materially impinges on the DNS and its operation. The draft uses clear language, is well motiovated and the discussion points arte clearly articulated. With the caveat that this reviiewer has no specific subject matter expertise in this area, the draft looks ready to me.
