XHTML is a separate language that began as a reformulation of HTML 4.01 using [[XML]] 1.0. It is now referred to as ''the XML syntax for HTML'' and is no longer being developed as a separate standard.<ref>{{cite web |title=HTML vs XML syntax |url=https://html.spec.whatwg.org/multipage/introduction.html#html-vs-xhtml |publisher=WHATWG |access-date=22 March 2023}}</ref>
* XHTML 1.0 was published as a W3C Recommendation on January 26, 2000,<ref>{{cite web |url=https://www.w3.org/TR/xhtml1/|title=XHTML 1.0: The Extensible HyperText Markup Language (Second Edition)|publisher=World Wide Web Consortium|date=January 26, 2000|access-date=November 16, 2008}}</ref> and was later revised and republished on August 1, 2002. It offers the same three variations as HTML 4.0 and 4.01, reformulated in XML, with minor restrictions.
* XHTML 1.1<ref>{{cite web |url=https://www.w3.org/TR/xhtml11/|title=XHTML 1.1 – Module-based XHTML&nbsp;— Second Edition|publisher=World Wide Web Consortium|date=February 16, 2007|access-date=November 16, 2008}}</ref> was published as a W3C Recommendation on May 31, 2001. It is based on XHTML 1.0 Strict, but includes minor changes, can be customized, and is reformulated using modules in the W3C recommendation "Modularization of XHTML", which was published on April 10, 2001.<ref>{{Cite web|url=https://www.w3.org/TR/2001/REC-xhtml-modularization-20010410/|title=Modularization of XHTML|website=W3C|access-date=2017-01-04}}</ref>
* XHTML 2.0 was a working draft. Work on it was abandoned in 2009 in favor of work on [[HTML5]] and [[XHTML#XHTML5|XHTML5]].<ref>{{cite web |url=https://www.w3.org/TR/xhtml2/|title=XHTM 2.0|publisher=World Wide Web Consortium|date=July 26, 2006|access-date=November 16, 2008}}</ref><ref>{{cite web |url=https://www.w3.org/News/2009#item119|title=XHTML 2 Working Group Expected to Stop Work End of 2009, W3C to Increase Resources on HTML5|publisher=World Wide Web Consortium|date=July 17, 2009|access-date=November 16, 2008}}</ref><ref>{{cite web|title=W3C XHTML FAQ|url=https://www.w3.org/2009/06/xhtml-faq.html}}</ref> XHTML 2.0 was incompatible with XHTML 1.x and, therefore, would be more accurately characterized as an XHTML-inspired new language than an update to XHTML 1.x.
