XHTML version
XHTML 1.0
XHTML 1.0 was released on January 20, 2000 as a W3C recommendation.
XHTML 1.0 version 2
XHTML 1.0 version 2 was released on August 1, 2002 as a W3C recommendation. It's not a new version, but an update and bug fixes.
About XHTML 1.0
XHTML 1.0 is the first major change to HTML since 1997 and a very important step on the road to delivering richer web pages to a wider range of user agents (agents) Including desktop computers, mobile devices, cell phones, and more.
XHTML is an XML application that migrates smoothly from HTML 4.01. The W3C's first step in refactoring HTML 4.01 to XML led to the birth of XHTML 1.0. XHTML 1.0 relies on the semantics provided by HTML 4.01 tags.
The next step is to modularize XHTML into a smaller set of elements, making it easier to combine XHTML with other markup languages (such as vector graphics and multimedia).
At the same time, the modularity of XHTML can also reduce development costs, improve collaboration with other applications (such as databases), make it easier to communicate with different user agents (browsers), and make HTML and different XML standards purer. integration.
W3C XHTML Activity
XHTML 1.0
XHTML 1.0 is a re-representation of HTML 4.01 using XML.

XHTML 1.1 (Modular XHTML)
Small devices (such as mobile phones) cannot support the full functionality of XHTML. XHTML 1.1 divides the specification into models with limited functionality. Small browsers can reduce complexity by supporting selected models (but once a model is selected, all of its features must be supported).
XHTML 1.1 is a strict language. XHTML 1.1 is not backwards compatible with HTML 4.
XHTML basics
XHTML Basic is a small subset of XHTML 1.1. It only contains basic XHTML features, such as text structure, images, basic bids, and basic tables. It is designed for small browsers (such as in handheld devices).
XHTML events
Thanks to support for W3C Document Object Model Level 2 in XHTML, event handlers can be attached to XHTML elements so that parent elements can handle events before or after child elements.

XHTML printing
XHTML-Print is part of XHTML 1.1 (Modular XHTML).
XHTML-Print is designed for use on mobile devices and cheap printers, which can often print a page from start to finish without print caching or a custom print driver for the device.
XForms
Through XHTML forms, users can access a page, add information to the page, and then submit the page to the web server.
XForms is the successor to HTML forms, providing a more complete and rendering-independent way of handling web interactive transactions. Because it is designed to integrate with XHTML, we expect that future e-commerce applications will require XForms.
To learn more about XForms, take our XForms tutorial.
XHTML modularity
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 (Document Type Definition).
XHTML 2.0 modularity is achieved through the use of XML Schemas.
To learn more about DTDs, take our DTD tutorial.
To learn more about XML Schemas, take our XML Schemas tutorial.
XHTML 2.0
XHTML 2.0 is the next generation of markup language. Its functionality is expected to be very 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 has stronger support for 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 in XHTML can represent hyperlinks, and how to traverse hyperlinks.
HLink is an extension to XLink.
