This document describes the registration of the MIME sub-type
application/xhtml+voice+xml. This sub-type is intended for use as a
media descriptor for XHTML+Voice multimodal language documents. The

Internet-Draft XHTML+Voice - application/xhtml+voice+xml April 2, 2004
2. Introduction
XHTML+VOice is a member of the XHTML family of document types, as
specified by XHTML Modularization. XHTML+Voice extends XHTML 1.1
[XHTML11] with a modularized subset of VoiceXML 2.0 [VXML20], XML
Events [XMLEVNTS], and a few extensions to both XHTML and VoiceXML
2.0. XHTML 1.1, VoiceXML 2.0 and XML Events are W3C Recommendations.
The language integration defined by XHTML+Voice supports all modules
defined by XHTML Modularization, and adds voice interaction to XHTML
elements to enable multimodal applications. The defined document
type for XHTML+VOice is XHTML Host language document type conformant.
XHTML+Voice 1.2 [XPLUSV12] is maintained by the VoiceXML Forum, at
URI location .
2.1 application/xhtml+voice+xml Usage
The application/xhtml+voice+xml media type is intended to be a media
descriptor for XHTML+Voice documents.
This media type registration is not intended for email usage.
3. IANA Registration
To: ietf-types@iana.org
Subject: Registration of Standard MIME media type
application/xhtml+voice+xml
MIME media type name: application
MIME subtype name: xhtml+voice+xml
Required parameters: none
Optional parameters:
version: refers to the XHTML+Voice language version in the document.
charset: has the same meaning as the text/html media type. See
section 2 of [RFC 2854].
Encoding considerations: 7bit. See section 4 of [RFC 2854].
Security considerations:
XHTML+Voice is an extension of XHTML and has the same security issues
as XHTML. These include interpreting anchors and forms in HTML
documents, and scripting languages and other dynamic interactive
capabilities. See section 7 of [RFC 2854].

Internet-Draft XHTML+Voice - application/xhtml+voice+xml April 2, 2004
Interoperability considerations :
Because XHTML+Voice is built upon W3C standard recommendations, it is
designed to be interoperable across a wide range of platforms and
client devices. Because the extensions to XHTML are identified by
their namespaces, all browsers that have namespace support can run an
XHTML+Voice document as an XHTML document without voice interaction.
Published specification:
The latest published version of XHTML+Voice is [XPLUSV12].
Applications which use this media type:
XHTML+Voice documents are intended to be deployed on the World
Wide Web and rendered by multimodal browsers that support the
visual and voice modes of interaction. See section 2 of
[RFC 2854].
Additional information:
Magic number(s): There is no single string that is always
present.
File extension(s): html, htm, mxml, xvml
Macintosh File Type Code(s): TEXT

See section 3 of [RFC 2854].
5. Recognizing XHTML+Voice files
Because XHTML+Voice is XML, an XHTML+Voice document [optionally]
starts with an XML declaration which begins with "
Because XHTML+Voice is in the XHTML family of languages, the root
element of an XHTML+Voice document is 'html' and '.
