Source: developerWorks : XML : Technical library For a while, there has been a struggle for the future of markup on the
web, a struggle between the W3C's XHTML 2 and HTML5, developed by the
major browser vendors under a separate organizational umbrella. First, the W3C
took over HTML5, and now it recently announced the sunset of the XHTML 2 effort. This
makes a significant difference to the future of XML on the web, and
furthermore, because of HTML5's momentum, it is now a technology
that every XML developer already has to deal with.
