XHTML Mobile Profile

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.

To validate as XHTML-MP, a document must contain a proper Document Type Declaration, or DOCTYPE, depending on the version of specification followed

Note that a series of revisions have been issued to correct technical errors in the above DTDs, and the DTD format is more complex and less widely supported than that of standard HTML.

The MIME type for XHTML Mobile Profile is "application/vnd.wap.xhtml+xml". Conforming user agents should also accept "application/xhtml+xml" and "text/html". Many desktop browsers will only validate XHTML-MP at display time, if an XML MIME type is specified.

A complete valid and well-formed example is:

When served with a MIME type of "application/xhtml+xml" or "application/vnd.wap.xhtml+xml".
