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.

This is now a Proposed Standard Protocol.

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.

This announcement is sent to the IETF list and the RFC-DIST list.
Requests to be added to or deleted from the IETF distribution list
should be sent to IETF-REQUEST@CNRI.RESTON.VA.US.  Requests to be
added to or deleted from the RFC-DIST distribution list should
be sent to RFC-DIST-REQUEST@ISI.EDU.
