Abstract

   This document is registration for the "example" media type and
   "example" subtypes within the standards tree.  The example/* and
   */example media types are defined for documentation purposes only.


1.  Introduction

   From time to time, documents created by the IETF or by other
   standards bodies show examples involving the use of media types,



Taylor                 Expires September 21, 2006               [Page 1]

Internet-Draft             Example media types                March 2006


   where the actual media type is not relevant.  It would be useful in
   such cases to be able to show a media type whose illustrative role in
   the example is clear.  In the worst case, this can be useful to debug
   implementations where the designer mistook the example for a
   requirement of the protocol concerned.

   To meet this need, this document registers the following media types:
   o  the example media type;
   o  the text/example, image/example, audio/example, video/example, and
      application/example media subtypes.


2.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].


3.  Registration of the example media type

   Type name: example.

   Subtype name: any subtype may be used with the example type.
   However, subtypes of example MUST NOT be registered.

   Required parameters: as invented by the user.

   Optional parameters: as invented by the user.

   Encoding considerations: as invented by the user.

   Security considerations: none.

   Interoperability considerations: none.

   Published specification: this document.

   Applications that use this media type: as invented by the user.

   Additional information:
      Magic number(s): not applicable.
      File extension(s): not applicable.
      Macintosh file type code(s): not applicable.

   Person & email address to contact for further information:

   Intended usage: LIMITED USE.

   Restrictions on usage: this type is intended only for use in
   documents providing examples involving specification of some media
   type, where the actual media type used is irrelevant.

4.  Registration of the text/example, image/example, audio/example,
    video/example, and application/example subtypes

   Type name: text, image, audio, video, and application.

   Subtype name: example.

   Required parameters: those required by the type and any others as
   invented by the user.

   Optional parameters: those offered by the type and any others as
   invented by the user.

   Encoding considerations: as invented by the user.

   Security considerations: none.

   Interoperability considerations: none.

   Published specification: this document.

   Applications that use this media type: as invented by the user.

   Additional information:
      Magic number(s): not applicable.
      File extension(s): not applicable.
      Macintosh file type code(s): not applicable.

   Person & email address to contact for further information:
   ietf-types@iana.org.

   Intended usage: LIMITED USE.

   Restrictions on usage: these subtypes are intended only for use in
   documents providing examples involving specification of some subtype
   of the given media type, where the actual subtype used is irrelevant.

5.  Security considerations

   The example media type and subtypes are defined for use in
   documentation only.  Hence they present no security issues other than
   those contrived by their user for purposes of illustration.


6.  IANA considerations

   This document specifies and registers the example media type and the
   text/example, image/example, audio/example, video/example, and
   application/example media subtypes.
