The Internet Assigned Number Authority (IANA) Application Configuration
            Access Protocol (ACAP) Vendor Subtrees Registry

Abstract

   The original Application Configuration Access Protocol (ACAP)
   specification included a vendor registry now used in other protocols.
   This document updates the description of this registry, removing the
   need for a direct normative reference to ACAP and removing ambiguity.

1.  Introduction

   The [ACAP] specification includes the specification and creation of
   the ACAP Vendor Registry, and this registry has subsequently been
   reused by several specifications, including both [ANNOTATE] and
   [METADATA], and is proving to be a useful mechanism for namespacing
   various names to within a specific vendor's scope.

   The use of textual rather than numeric identifiers for vendors
   benefits engineers and operators who are diagnosing protocol problems
   by allowing them some possibility of identifying the origin of a
   vendor attribute without having to look it up in a registry (although
   that remains a necessary fallback).  As such, engineers and operators
   already have to be familiar with international technical English to
   diagnose textual protocol problems, the restriction to ASCII may help
   and is not believed to harm that intended use.  Exposure of vendor
   attributes directly in end-user user interfaces was not an intended
   use of the registry.

   This document merely updates the registry to reduce ambiguity in the
   original specification and dissociates it from the original document
   in all but name, allowing easier referencing.  It replaces Section
   7.4 and portions of Section 4, particularly Section 4.3, of [ACAP].
