Abstract

MIME [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 MIME type. 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 document is only a minor revision to the text/enriched MIME type that was first described in [RFC-1523] and [RFC-1563], and is only intended to be used in the short term until other MIME types for text formatting in Internet mail are developed and deployed.

Abstract

   MIME [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

   MIME type. 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 document is only a minor

   revision to the text/enriched MIME type that was first described in

   [RFC-1523] and [RFC-1563], and is only intended to be used in the

   short term until other MIME types for text formatting in Internet

   mail are developed and deployed.

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. The content-type

   line for this type may have one optional parameter, the "charset"

   parameter, with the same values permitted for the "text/plain" MIME

   content-type.

   The text/enriched 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 can

      represent no more than is likely to be representable by the

      user's primary word processor. While this limits what can be

      sent, it increases the likelihood that what is sent can be

      properly displayed.

   There are other text formatting standards which meet some of these

   criteria. In particular, HTML and SGML have come into widespread use

   on the Internet. However, there are two important reasons that this

   document further promotes the use of text/enriched in Internet mail

   over other such standards:

   1. Most MIME-aware Internet mail applications are already able to

      either properly format text/enriched mail or, at the very least,

      are able to strip out the formatting commands and display the

      readable text. The same is not true for HTML or SGML.

   2. The current RFC on HTML [RFC-1866] and Internet Drafts on SGML

      have many feature...
