Hello Authors, Now that we have all necessary content approvals, we have converted the kramdown-rfc file to RFCXML. We made some additional formatting changes in the XML file, including reference updates.
We also have additional comments for your review: 1) Upon completing the XML conversion, we came across a bug in the updated WHATWG-IPV4 reference, specifically in the TXT output. We have filed an issue with the Tools Team; see https://github.com/ietf-tools/xml2rfc/issues/1308 for further clarification. 2) We have updated RFCs 8446 and 8447 to RFC-to-be-9846 and RFC 9847 per Sean Turner’s mail from 2 December 2025. With these reference updates, please review the updated files and let us know if any updates are needed to the current in-text citations for these RFCs. Please review the XML file and its TXT, HTML, and PDF outputs, and let us know if any changes are required or if you approve the RFC for publication. While this is your approval of the XML and its outputs, we consider this your final assent that the document is ready for publication. To request changes or approve your RFC for publication, please reply to this email. Please use ‘REPLY ALL’, as all the parties CCed on this message need to see your approval. Please note that we will only make changes in the XML file from this point on.
