Abstract 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 XHTML+Voice 1.2 language specification is maintained by the VoiceXML Forum at . 1.

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]. McCobb Expires October 2, 2004 [Page 2] 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 Person & email address to contact for further information: Gerald M. McCobb mccobb@us.ibm.com Intended usage: COMMON Author/Change controller: Gerald McCobb Further information: 4. Fragment Identifiers 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 '.
