XHTML 2 development dropped for HTML 5
The W3C (World Wide Web Consortium), the main standards organization for the World Wide Web, has said that they would stop further development for the markup language XHTML 2 to increase available resources for the development of HTML 5.
HTML, before HTML 5, was an application of SGML, which requires a complex specification because it was more flexible. XHTML is an application of XML, a version of SGML, which has a stricter, and therefore simpler, specification. XHTML has been a W3C recommendation since January 26, 2000.
Rich Internet Add-ons
InfoWorld has examined if HTML 5 could kill rich internet add-ons like Flash and Silverlight. HTML 5 offers technologies such as Canvas, for 2-D drawing on a page, which can compete with technologies such as Adobe Flash and Microsoft Silverlight and eliminate the need for users to install plugins for full website functionality. This will not happen for a long time, so until then, developers will continue to use existing technologies.
In addition to replacements for rich internet add-ons, HTML 5 also includes elements that are semantic replacements for generic block (
<div>) and inline (
<span>) elements, for example
Also, some purely presentational elements that have been depreciated in HTML 4.01, such as
<center>, have been removed because these effects should be achieved using CSS
To fix bugs, maintenance work will continue to be done by the W3C with XHTML 1.1.
