The IESG has approved the following document: - 'Updating when Standards Track Documents may Refer Normatively to Documents at a Lower Level' (draft-leiba-3967upd-downref-03.txt) as Best Current Practice This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-leiba-3967upd-downref/ Technical Summary RFC 3967 specifies a process for allowing normative references to documents at lower maturity levels ("downrefs"), which involves calling out the downref explicitly in the last call notice. That requirement has proven to be unnecessarily strict, and this document updates RFC 3967, allowing the IESG more flexibility in accepting downrefs in Standards Track documents. Working Group Summary This is an AD sponsored draft. Comments prior to and during IETF last call have been favorable. Document Quality Given that this is a process draft, the implementers would be the IESG itself. Personnel The responsible AD is Ben Campbell.
