Abstract

MIME [RFC-1341, RFC-1521] defines a format and general framework for the representation of a wide variety of data types in Internet mail. This document defines one particular type of MIME data, the text/enriched type, a refinement of the "text/richtext" type defined in RFC 1341. The text/enriched MIME type is intended to facilitate the wider interoperation of simple enriched text across a wide variety of hardware and software platforms. This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind.

The Text/enriched MIME type

In order to promote the wider interoperability of simple formatted text, this document defines an extremely simple subtype of the MIME content-type "text", the "text/enriched" subtype. This subtype was designed to meet the following criteria:

1. The syntax must be extremely simple to parse, so that even teletype-oriented mail systems can easily strip away the formatting information and leave only the readable text.

2. The syntax must be extensible to allow for new formatting commands that are deemed essential for some application.

3. If the character set in use is ASCII or an 8- bit ASCII superset, then the raw form of the data must be readable enough to be largely unobjectionable in the event that it is displayed on the screen of the user of a non-MIME-conformant mail reader.

4. The capabilities must be extremely limited, to ensure that it ca...
