Abstract

This document proposes new media sub-types of Text/SGML and Application/SGML. These media types can be used in the exchange of SGML documents and their entities. Specific details for the exchange or encapsulation of groups of related SGML entities using MIME are currently being considered by the mimesgml Working Group .

Abstract

This document proposes new media sub-types of Text/SGML and

Application/SGML. These media types can be used in the exchange of

SGML documents and their entities. Specific details for the exchange

or encapsulation of groups of related SGML entities using MIME are

currently being considered by the mimesgml Working Group

1. Introduction

A need exists for the transfer the elements of documents constructed

using the Standard Generalized Markup Language (SGML) [ISO-8879].

While the specific details of such transfers are being considered

general agreement exists on the need to register basic media types

for the SGML entities not covered by existing types.

The Standard Generalized Markup Language (SGML) is used to encode

document structure and a rigorous description of it is left to [ISO-

8879]. The terms used in the present document attempt to be

consistent with SGML terminology and usage.

2. The SGML Media-Types

There are two media-types for SGML parsable entities, Text/SGML and

Application/SGML. Both have the same optional parameters. Text/SGML

provides a fallback to Text/Plain for those without SGML capability.

Senders should base the choice between text and application media-

types on the entity's content. Text is suggested for entities that

would be meaningful to a human being without SGML processing.

Application/SGML is recommended for all others.

2.1. Text/SGML

MIME type name: Text

MIME subtype name: SGML

Required parameters: none

Optional parameters: charset, SGML-bctf, SGML-boot

Encoding considerations: may be encoded

Security considerations: see section 4 below

Published specification: ISO 8879:1986

The Text/SGML media-type can be employed when the contents of the

SGML entity is intended to be read by a human and is in a readily

comprehensible form. That is the content can be easily discerned by

someone without SGML display software. Each record in the SGML

entity, delimited by record start (RS) and record end (RE) codes,

must correspond to a line in the Text/SGML body part.

SGML entities that do not meet the above requirements should use the

Application/SGML media-type.
