Reviewer: Christian Amsüss Review result: Ready with Nits Reviewer's summary: The document touches right on typical ART issues such as the hard parts of internationalization and evolution -- but works in a space where there is little room for change, and applies technical enhancements where it can. Apart from technical fixes, it has relatively stern words for registries that ignored the already existing guidance that is emphasized and precised in this document; whether that can lead to a change in behavior is beyond what I can confidently make predictions about. I consider the document ready; the issues below are minor enough that they should easily be addressable by the authors and the RFC editor without further review. Unclear errata handling: * Erratum 5484 is bundled with the group of 63-character-A-label vs. 252-octet-U-label, when <https://www.rfc-editor.org/errata/eid5484> looks completely unrelated. Editorial remarks: * Section 4, the paragraph "Rules requiring strict" gave the right gist at quick skimming, but took several attempts for me to fully parse in detail. It might be easier to consume with simplified sentence structure. * "When RFC 5891 is actually updated": This document does update 5891 if approved, and the Unicode references are relatively recent -- is this a leftover comment from during editing, or more of a remark to the RFC editor? Editorial nits: * "Section 2.3.2.3 of the Definitions document" would be more usable as a deep link into the RFC, samey with any later occurrence of "Section" that is not a link. * "IDNA2008" and "IDNA 2008" is inconsistently used with and without the space character. * 5.2 New, has more closing than open parantheses, the closing parenthesis after UnicodeB should be removed. -- last-call mailing list -- last-call@xxxxxxxx To unsubscribe send an email to last-call-leave@xxxxxxxx
