Network Working Group T. Taylor Internet-Draft Nortel Expires: September 21, 2006 March 20, 2006 Example media types for use in documentation draft-taylor-types-example-00.txt Status of this Memo By submitting this Internet-Draft, each author represents that any applicable patent or other IPR claims of which he or she is aware have been or will be disclosed, and any of which he or she becomes aware will be disclosed, in accordance with Section 6 of BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet- Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

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: ietf-types@iana.org. Taylor Expires September 21, 2006 [Page 2] Internet-Draft Example media types March 2006 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. Author: Internet Engineering Task Force Change controller: Internet Engineering Task Force 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.

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. 7.
