McCobb Internet-Draft IBM Corporation Expires: Oct. 1, 2005 April 1, 2005 XHTML+Voice - application/xhtml+voice+xml draft-mccobb-xplusv-media-type-02 Status of this Memo By submitting this Internet-Draft, I certify that any applicable patent or other IPR claims of which I am aware have been disclosed, and any of which I become aware will be disclosed, in accordance with RFC 3668.

Copyright Notice Copyright (C) The Internet Society (2004). All Rights Reserved 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 <http://www.voicexml.org/specs/multimodal/x+v/12/>. 1. Conventions used in this document 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 BCP 14, RFC 2119 [RFC2119]. McCobb Expires Oct. 1, 2005 [Page 1] Internet-Draft XHTML+Voice - application/xhtml+voice+xml April 1, 2005 2. Introduction XHTML+Voice is a member of the XHTML family of document types, as specified by XHTML Modularization [XHTMLMOD]. 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 <http://www.voicexml.org/specs/multimodal/x+v/12/>. 2.1 application/xhtml+voice+xml Usage The application/xhtml+voice+xml media type is intended to be a media descriptor for XHTML+Voice multimodal documents. Multimodal browsers have special processing requirements for XHTML+Voice documents, such as running a voice browser component, and support for the DOM Level 2 Event Model [DOM2EV] and XML Events [XMLEVNTS]. 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: charset: has the same semantics as the charset parameter of the "application/xml" media type specified in [RFC3023]. Encoding considerations: 7bit. See section 4 of [RFC3236]. Security considerations: XHTML+Voice is an extension of XHTML and has the same security issues McCobb Expires Oct. 1, 2005 [Page 2] Internet-Draft XHTML+Voice - application/xhtml+voice+xml April 1, 2005 as XHTML. These include interpreting anchors and forms in XHTML documents, and scripting languages and other dynamic interactive capabilities. See section 7 of [RFC3236]. In addition, the scripting language can be accessed by both the XHTML and the VoiceXML 2.0 markup embedded in the XHTML+Voice document. See section 1.3.1.5 of [XPLUSV12]. 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. Because XHTML+Voice is an application of XML, authors can expect XHTML+Voice user agents to be conformant XML 1.0 [XML] processors. See section 2 of [RFC3236]. Additional information: Magic number(s): There is no single string that is always present. File extension(s): mxml, xhvml, xvml, xvm 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 [RFC3236]. Following [RFC3236], fragment McCobb Expires Oct. 1, 2005 [Page 3] Internet-Draft XHTML+Voice - application/xhtml+voice+xml April 1, 2005 identifiers for XHTML+Voice documents designate the element with the corresponding ID attribute value (see [XML] section 3.3.1). While XHTML+Voice adds new ID attributes with fragment identifier namespaces that are not in the same namespace as XHTML, the fragment identifiers are processed in the same namespace as the ID attribute's namespace. 5. Recognizing XHTML+Voice files Because XHTML+Voice is XML, an XHTML+Voice document [optionally] starts with an XML declaration which begins with "<?xml" and has a DOCTYPE declaration "<!DOCTYPE html". XHTML+Voice 1.2 has the following DOCTYPE declaration: <!DOCTYPE html PUBLIC "-//VoiceXML Forum//DTD XHTML+Voice 1.2//EN" "http://www.voicexml.org/specs/multimodal/x+v/12/dtd/xhtml+voice12.dtd"> Because XHTML+Voice is in the XHTML family of languages, the root element of an XHTML+Voice document is 'html' and '<html' can be found near the top of the document. 6. Security Considerations Security considerations for this media type are discussed in the MIME type registration that appears in section 3. 7.
