Participants made changes as reflected in IPNNI-2020-00059R000. Instances of “delegated certificates” were changed to “delegate certificates”, except when referring to all three viable mechanisms: Delegated Certificates, Extended Validation (EV) Certificates with Telephone Number Letter of Authorization (TNLoA), and Central TN Database. Participants also discussed the fact that this document contains references to draft TRs. A clarification was made that this document represents a moment in time when a decision was made on how to move forward. Draft RFCs contain language pointing to the most recent version of a document; however, this TR references the draft baselines as they stood when this TR was approved, without any edits that may be approved in the future. A suggestion was made to zip the referenced baselines as referenced with this publication. This matter will be further discussed offline. An agreement was reached that all the changes were made were non-substantive, and these comments were accepted as modified in IPNNI-2020-00059R001.
