Schema rb not updating
The specification became a W3C recommendation on December 2000.Of all the versions of XHTML, XHTML Basic 1.0 provides the fewest features.The WHATWG eventually began working on a standard that supported both XML and non-XML serializations, HTML5, in parallel to W3C standards such as XHTML 2.In 2007, the W3C's HTML working group voted to officially recognize HTML5 and work on it as the next-generation HTML standard.HTML 4 was ostensibly an application of Standard Generalized Markup Language (SGML); however the specification for SGML was complex, and neither web browsers nor the HTML 4 Recommendation were fully conformant to it.There are various differences between XHTML and HTML.The Document Object Model (DOM) is a tree structure that represents the page internally in applications, and XHTML and HTML are two different ways of representing that in markup (serializations).
In addition to the Core Modules (Structure, Text, Hypertext, and List), it implements the following abstract modules: Base, Basic Forms, Basic Tables, Image, Link, Metainformation, Object, Style Sheet, and Target.
In the current XHTML 1.0 Recommendation document, as published and revised to August 2002, the W3C commented that, "The XHTML family is the next step in the evolution of the Internet.
By migrating to XHTML today, content developers can enter the XML world with all of its attendant benefits, while still remaining confident in their content's backward and future compatibility." However, in 2005, the Web Hypertext Application Technology Working Group (WHATWG) formed, independently of the W3C, to work on advancing ordinary HTML not based on XHTML.
By February 1999 the name of the specification had changed to XHTML 1.0: The Extensible Hyper Text Markup Language, and in January 2000 it was officially adopted as a W3C Recommendation.
Modularization provides an abstract collection of components through which XHTML can be subsetted and extended.
