Document: draft-ietf-acme-tls-alpn-06 Reviewer: Linda Dunbar Review Date: 2019-09-20 IETF LC End Date: 2019-09-25 IESG Telechat date: Not scheduled for a telechat Summary: This document specifies a new "challenges" for Automated Certificate Management Environment Major issues: Minor issues: Nits/editorial comments: The 3rd paragraph of the Introduction stated that this New Challenges requires negotiating a new application layer protocol, but no existing software implements this protocol. Therefore the ability to fulfill this challenges is effectively "opt-in". I find the statement is quite confusing. Does it mean that it is necessary to manually add processing to handle the challenge because there is no implementation of auto negotiation? Thanks, Linda Dunbar
