Updating When Standards Track Documents May Refer Normatively to Documents at a Lower Level
RFC 8067, “Updating When Standards Track Documents May Refer Normatively to Documents at a Lower Level”, is a Best Current Practice document published in January 2017 by B. Leiba. It updates RFC 3967. The canonical text is published by the RFC Editor.
Abstract
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.
What “Best Current Practice” means
Documents the IETF community's recommended operational or procedural practice rather than a protocol specification.
