The World Wide Web Consortium (W3C) released XHTML Basic as a W3C Recommendation. The specification reflects cross-industry agreement on a set of markup language features that allows authors to create rich Web content deliverable to a wide range of devices, including mobile phones, personal digital assistants (PDAs), pagers, and television-based Web browsers. A W3C Recommendation indicates that a specification is stable, contributes to Web interoperability, and has been reviewed by the W3C Membership, who favor its adoption by the industry. In January 2000, W3C published the XHTML 1.0 Recommendation, which combined the well-known features of HTML with the power of XML. In another W3C specification entitled “Modularization of XHTML”, W3C’s HTML Working Group describes a mechanism that allows authors to mix and match content from well-defined subsets of XHTML 1.0 elements and attributes. The XHTML Basic Recommendation combines some of these XHTML modules in a manner well-suited to mobile Web applications. XHTML Basic is designed so that it may be implemented by all user agents, including mobile devices, television-based devices, and other small Web devices. The XHTML Basic specification is the result of significant collaborative efforts of the W3C HTML Working Group, including participants from AOL/Netscape; CWI; Ericsson; IBM; Intel; Matsushita Electric Industrial Co., Ltd.; Microsoft; Mozquito Technologies; Openwave Systems Inc.; Philips Electronics; Quark Inc.; and Sun Microsystems. In addition, the Working Group integrated feedback from the W3C Mobile Access Interest Group and the WAP Forum in an effort to ensure demonstrable functionality in wireless devices. Many industry players support, or have plans to support, XHTML Basic, including the WAP Forum. Today, content developers interested in making XHTML Basic documents can create them with W3C’s own browser/editor, Amaya. www.w3.org/
