   This document describes a new sub-delegation for the 'ietf' URN
   namespace for registered protocol items.  The 'ietf' URN namespace is
   defined in RFC 2648 as a root for persistent URIs that refer to
   IETF-defined resources.

1.  Introduction

   From time to time IETF standards require the registration of various
   protocol elements in well known central repository.  The Internet
   Assigned Numbers Authority maintains this central repository and
   takes direction from the IETF on what, how and when to add items to
   it.  The IANA maintains lists of items such as all assigned port
   numbers, MIME media types, enterprise numbers, etc.

   Over time there has developed a need to be able to reference these
   elements as URIs in various schema.  In the past this was done in a
   very ad hoc way that easily led to interoperability problems.  This
   document creates a new sub-delegation below the "ietf" [2]URN
   namespace [1] called 'params' which acts as a standardized mechanism
   for naming the items registered for IETF standards.  Any assignments
   below that are specified in an RFC according to the IETF consensus
   process and which include the template found in Section 4.
