                   The Model Primary Content Type for
                 Multipurpose Internet Mail Extensions

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Introduction

   The purpose of this memo is to propose an update to Internet RFC 2045
   to include a new primary content-type to be known as "model". RFC
   2045 [1] describes mechanisms for specifying and describing the
   format of Internet Message Bodies via content-type/subtype pairs. We
   believe that "model" defines a fundamental type of content with
   unique presentational, hardware, and processing aspects.  Various
   subtypes of this primary type are immediately anticipated but will be
   covered under separate documents.
