1 Introduction

   Recent Internet applications, such as the World Wide Web, tie
   together a great diversity in data formats, client and server
   platforms, and communities.  This has created a need for media
   feature descriptions and negotiation mechanisms in order to identify
   and reconcile the form of information to the capabilities and
   preferences of the parties involved.

   Extensible media feature identification and negotiation mechanisms
   require a common vocabulary in order to positively identify media
   features.  A registration process and authority for media features is
   defined with the intent of sharing this vocabulary between
   communicating parties. In addition, a URI tree is defined to enable
   sharing of media feature definitions without registration.

   This document defines a registration procedure which uses the
   Internet Assigned Numbers Authority (IANA) as a central registry for
   the media feature vocabulary.

   This document uses the terms MUST, MUST NOT, SHOULD, SHOULD NOT and
   MAY according to usage described in [8].
