XHTML Mobile Profile (XHTML MP) is a hypertextual computer language standard designed specifically for mobile phones and other resource-constrained devices. It is an XHTML document type defined by the Open Mobile Alliance. XHTML-MP is derived from XHTML Basic 1.0 by adding XHTML Modules, with later versions of the standard adding more modules. However, for certain modules, XHTML-MP does not mandate a complete implementation so an XHTML-MP browser may not be fully conforming on all modules.The XHTML MP 1.2 DTD is the current recommendation, finalized in March 2008. XHTML Basic 1.1 became a W3C Recommendation in July 2008, superseding XHTML-MP 1.2.
