This is a request to register the application/x-www-form-urlencoded media
type by reference to the HTML5 specification:


Type name:

Subtype name:

Required parameters:
  No parameters

Optional parameters:
  No parameters

Encoding considerations:
  7bit (US-ASCII encoding of octets that themselves can be encoding text
  using any ASCII-compatible character encoding)

Security considerations:
  In isolation, an application/x-www-form-urlencoded payload poses no
  security risks. However, as this type is usually used as part of a form
  submission, all the risks that apply to HTML forms need to be considered
  in the context of this type.

Interoperability considerations:
  Rules for generating and processing application/x-www-form-urlencoded
  payloads are defined in the HTML5 specification.

Published specification:
  The HTML specification is the relevant specification. Algorithms for
  encoding and decoding are defined.

Applications that use this media type:
  Web browsers and servers.

Additional information:
  Magic number(s):
    There is no reliable mechanism for recognizing
    application/x-www-form-urlencoded payloads.

  File extension(s):
    Not applicable.

  Macintosh file type code(s):
    Not applicable.

Person & email address to contact for further information:
  Michael[tm] Smith <mike@w3.org>

Intended usage:

Restrictions on usage:
  This type is only intended to be used to describe HTML form submission

  Ian Hickson <ian@hixie.ch>

Change controller:

Fragment identifiers have no meaning with the application/x-www-form-urlencoded
type as this type is only used for uploaded payloads that do not have URL
