Abstract

   This document defines the 'application/xhtml+xml' MIME media type for

   XHTML based markup languages; it is not intended to obsolete any

   previous IETF documents, in particular RFC 2854 which registers

   'text/html'.

1. Introduction

   In 1998, the W3C HTML working group began work on reformulating HTML

   in terms of XML 1.0 [XML] and XML Namespaces [XMLNS].  The first part

   of that work concluded in January 2000 with the publication of the

   XHTML 1.0 Recommendation [XHTML1], the reformulation for HTML 4.01

   [HTML401].

   Work continues in the Modularization of XHTML Recommendation

   [XHTMLM12N], the decomposition of XHTML 1.0 into modules that can be

   used to compose new XHTML based languages, plus a framework for

   supporting this composition.

   This document only registers a new MIME media type,

   'application/xhtml+xml'.  It does not define anything more than is

   required to perform this registration.

RFC 3236         The 'application/xhtml+xml' Media Type     January 2002

   This document follows the convention set out in [XMLMIME] for the

   MIME subtype name; attaching the suffix "+xml" to denote that the

   entity being described conforms to the XML syntax as defined in XML

   1.0 [XML].

   This document was prepared by members of the W3C HTML working group

   based on the structure, and some of the content, of RFC 2854, the

   registration of 'text/html'.  Please send comments to www-

   html@w3.org, a public mailing list (requiring subscription) with

   archives at <http://lists.w3.org/Archives/Public/www-html/>.

2. Registration of MIME media type application/xhtml+xml

    MIME media type name:      application

    MIME subtype name:         xhtml+xml

    Required parameters:       none

    Optional parameters:

      charset

         This parameter has identical semantics to the charset parameter

         of the "application/xml" media type as specified in [XMLMIME].

      profile

         See Section 8 of this document.

   Encoding considerations:

      See Section 4 of this document.

   Security considerations:

      See Section 7 of this document.

   Interoperability considerations:

      XHTML 1.0 [XHTML10] specifies user agent conformance rules that

      dictate behaviour that must be followed when dealing with, among

      other things, unrecognized elements.

      With respect to XHTML Modularization [XHTMLMOD] and the existence

      of XHTML based languages (referred to as XHTML family members)

      that are not XHTML 1.0 conformant languages, it is possible that

      'application/xhtml+xml' may be used to describe some of these

      documents.  However, it should suffice for now for the purposes of

      interoperability that user agents accepting
