1. Introduction
This document is a companion to [1], which defines the principles
behind interworking between MIME-based RFC-822 mail and X.400 mail.
This document describes the content of the "IANA MHS/MIME Equivalence
table" referenced in the companion document, and defines the initial
configuration of this table. Mappings for new MIME content-types
and/or X.400 body part types should be registered with the IANA to
minimize redundancy and promote interoperability.
In MIME, the term "content-type" is used to refer to an information
object contained in the body of a message. In contrast, X.400 uses
the term "body part type." In this document, the term "body part" is
used to refer to either.
Please send comments to the MIME-MHS mailing list:
<mime-mhs@surfnet.nl>.
2. Equivalence Table Definition
For each MIME content-type/X.400 body part pair, the Equivalence
Table will contain an entry with the following sections:
X.400 Body Part
This section identifies the X.400 Body Part governed by this
Table entry. It includes any OBJECT IDENTIFIERs or other
parameters necessary to uniquely identify the Body Part.
MIME Content-Type
This section identifies the MIME content-type governed by this
