Description

XHTML 1.0 is a reformulation of HTML 4 as an XML 1.0 application. The specification defines three DTDs corresponding to the ones defined by HTML 4. The semantics of the elements and their attributes are defined in the W3C Recommendation for HTML 4, and provide the foundation for future extensibility of XHTML. Compatibility with existing HTML user agents is possible by following a small set of guidelines. XHTML 1.1 reformulates HTML as a set of modules, and XHTML Basic creates a subset of XHTML for use on smaller devices. XHTML 2.0 is now under development, and represents the first major changes to the HTML vocabulary since HTML 4.0.
