W3C XHTML Activities
HTML is the universal markup language for the Web.
To see how this Web Site was converted to XHTML, read our XHTML
XHTML 1.0 became a W3C Recommendation 20. January 2000.
XHTML 1.0 Second Edition
XHTML 1.0 Second Edition became a W3C Recommendation 1. August 2002.
The second edition is not a new version, but an update and a "bug-fix".
About XHTML 1.0
XHTML 1.0 was the first major change to HTML since 1997, and a very important
step to create a standard that will provide richer web pages on a wider
range of user agents (browsers), like desktop PCs, mobile (wireless) devices,
and cell phones.
XHTML 1.0 reformulates HTML 4.01 in XML. XHTML
1.0 relies on HTML 4.01 for the meanings of the HTML tags.
W3C's next step includes modularization of XHTML into smaller element
collections, to make it easier to combine XHTML with other markup languages, like
vector graphics and multimedia.
Modularization of XHTML also gives reduced development costs, improved
cooperation with other applications (like databases), easier communication with
different user agents (browsers), and cleaner integration between HTML and
different XML standards.

XHTML 1.1 (Modular XHTML)
Small devices cannot support all XHTML functions, therefore XHTML 1.1 divides the specification into modules with limited
Small browsers can reduce their complexity by
supporting only selected modules.
XHTML 1.1 is a strict language. XHTML 1.1 is not backward compatible with HTML 4.
XHTML Basic is a small subset of XHTML 1.1. It contains only
the basic XHTML features like text structure, images, forms, and
tables. It is designed for small browsers (like in handheld devices).
With support for the DOM in XHTML, event
handlers can be attached to XHTML elements so that parent elements can handle
events before and after child elements.
To learn more about the DOM, study our DOM tutorial.
XHTML-Print is a part of XHTML 1.1.
XHTML-Print is designed for mobile devices and low-cost printers that
generally print from top to bottom of a page with no printing buffer and without
a device-specific printer driver.
XForms are the successors of HTML forms. XForms provides a richer and
presentation independent way of handling interactive Web transactions. Designed
to be integrated with XHTML, we can expect that future e-commerce applications
will demand the use of XForms.
To learn more about XForms, study our XForms tutorial.
XHTML 2.0 is expected
to remain similar to XHTML 1.1, but the markup language may be altered to
conform to the requirements of XML standards like XML Linking and XML
XLink is a language for creating hyperlinks in XML documents. XLink is
similar to HTML links - but it is a lot more powerful.
You can learn more about XLink in
our XLink tutorial.
HLink is an extension to XLink, and it specifies which attributes of elements represent
hyperlinks in XHTML, and specifies how hyperlinks should be traversed.
