X.400 1988 to 1984 downgrading
Overview
RFC 1328, “X.400 1988 to 1984 downgrading”, is a Historic document published in May 1992 by S. Hardcastle-Kille. The canonical text is published by the RFC Editor.
Abstract
This document considers issues of downgrading from X.400(1988) to X.400(1984) [MHS88a, MHS84]. Annexe B of X.419 specifies some downgrading rules [MHS88b], but these are not sufficient for provision of service in an environment containing both 1984 and 1988 components. This document defines a number of extensions to this annexe. [STANDARDS-TRACK]
