     A Framework for DNSSEC Policies and DNSSEC Practice Statements

Abstract

   This document presents a framework to assist writers of DNS Security
   Extensions (DNSSEC) Policies and DNSSEC Practice Statements, such as
   domain managers and zone operators on both the top level and
   secondary level, who are managing and operating a DNS zone with
   Security Extensions implemented.

   In particular, the framework provides a comprehensive list of topics
   that should be considered for inclusion into a DNSSEC Policy
   definition and Practice Statement.
