XHTML Mobile Profile

A list of errata and updates to this document is available from the WAP Forum™ Web site, in the form of SIN documents, which are subject to revision or removal without notice. 1. Scope Wireless Application Protocol (WAP) is a result of continuous work to define an industry-wide specification for developing applications that operate over wireless communication networks. The scope for the WAP Forum is to define a set of specifications to be used by service applications. The wireless market is growing very quickly and reaching new customers and services. To enable operators and manufacturers to meet the challenges in advanced services, differentiation, and fast/flexible service creation, WAP defines a set of protocols in transport, session, and application layers. For additional information on the WAP architecture, refer to [WAPARCH]. This specification defines an XHTML document type based upon the module framework and the modules defined by Modularization of XHTML [XHTMLMod]. This document type is called XHTML Mobile Profile and is designed for resource-constrained Web clients that do not support the full set of XHTML features, such as mobile phones, PDAs, pagers and set-top boxes. It extends XHTML Basic with modules, elements and attributes to provide a richer authoring language. 2.2.

Introduction The motivation for the XHTML Mobile Profile document type is to provide an authoring language based upon XHTML that addressed the special requirements of Web clients operating on resource-constrained devices such as mobile phones. The XHTML Mobile Profile is a strict subset of XHTML. It extends XHTML Basic to bring enhanced functionality to application authors, including additional presentation elements and support for internal style sheets. 5. The XHTML Mobile Profile Document Type The XHTML Mobile Profile document type is an XHTML document type based upon the module framework and the modules defined by [XHTMLMod]. The XHTML Mobile Profile document type is defined as a strict superset of [XHTMLBasic]. XHTML Mobile Profile consists of the XHTML modules specified in this section. All XHTML modules are defined in [XHTMLMod]. XHTML Basic Module Element Structure body, head, html, title Text abbr, acronym, address, blockquote, br, cite, code, dfn, div, em, h1, h2, h3, h4, h5, h6, kbd, p, pre, q, samp, span, strong, var Hypertext a List dl, dt, dd, ol, ul, li Basic Forms form, input, label, select, option, textarea Basic Tables caption, table, td, th, tr Image img Object object, param Metainformation meta Link link Base base For modules marked as partial above, the module was not included in its entirety (only selected elements were included). The implication of this is that the XHTML Mobile Profile document type is not strictly XHTML Host Language Conforming, as defined in [[XHTMLMod]]. An implementation of this document type as an XML 1.0 DTD is available in Appendix A. The elements, attributes and minimum content models associate
