XHTML 1.0 ¶

As a W3C recommendation, XHTML 1.0 was released on January 26, 2000.

XHTML 1.0 Revision ¶

As a W3C recommendation, the second version of XHTML 1.0 was released on August 1, 2002. It is not a new version, but an update and bug fix.

XHTML 1.1 ¶

As a W3C recommendation, XHTML 1.1 was released on May 31, 2001.

XHTML 1.12nd Edition ¶

As a W3C recommendation, XHTML 1.1 (SE) was released on November 23, 2010.

XHTML 1.0 ¶

XHTML 1.0 is a rerepresentation of HTML 4.01 using XML.

XHTML 1.1 (modular XHTML) ¶

Small devices, such as mobile phones, cannot support all the features of XHTML. XHTML 1.1 divides the specification into models with limited functionality. Small browsers can reduce their complexity by supporting selected models (but once a model is selected, it must support all its features).

XHTML 1.1 is a strict language. XHTML 1.1 is not backward compatible with HTML 4.

XHTML Foundation ¶

XHTML Basic is a small subset of XHTML 1.1. It contains only basic XHTML features, such as text structure, images, basic bids, and basic tables. It is designed for small browsers (for example, in handheld devices).

XHTML event ¶

Because of the support for W3C document object model level 2 in XHTML, the event handler can attach to the XHTML element so that the parent element canhandle events before or after the child element.

XHTML printing ¶

XHTML-Print is part of XHTML 1.1 (modular XHTML).

XHTML-Print is designed for mobile devices and cheap printers, which usuallyprint a page from beginning to end without a print cache and a custom printdriver for the device.

XForms ¶

Through the XHTML form, users can access a page, add information to the page, and then submit the page to the Web server.

XForms, the successor to HTML forms, provides a more complete and rendering-independent way to handle Web transactions. As it is designed to integrate with XHTML, we expect that future e-commerce applications will require XForms.

XHTML modularization ¶

XHTML modularity refers to the division of XHTML 1.0 into a collection of small models that provide specific functionality.

The modularity of XHTML 1.0 is achieved through the use of XML DTD (DocumentType Definition).

The modularity of XHTML 2.0 is achieved through the use of XML Schemas.

To learn more about DTD, please learn our DTD tutorial.

To learn more about XML Schemas, please learn our XML Schemas tutorial.

XHTML 2.0 ¶

XHTML 2.0 is the next generation markup language. Its functionality is expected to be similar to XHTML 1.1, but may be changed to comply with the requirements of XML standards, such as XML Linking and XML Schema.

XLink ¶

XLink is a language for creating hyperlinks in XML documents. XLink is similar to HTML links-but more strongly supports simple links (such as HTML)and extended links (used to link multiple resources together).

You can learn more about XLink in our XLink tutorial.

HLink ¶

HLink adds the ability to specify which elements can represent hyperlinks inXHTML and how to traverse hyperlinks.

HLink is an extension of XLink.
