HTML5 is the main focus of the WHATWG community and also that of the W3C HTML Working Group. HTML5 is a new version of HTML4, XHTML1, and DOM Level 2 HTML addressing many of the issues of those specifications while at the same time enhancing (X)HTML to more adequately address Web applications. Besides defining a markup language that can be written in both HTML (HTML5) and XML (XHTML5) it also defines many APIs that form the basis of the Web architecture. Some of these APIs were known as “DOM Level 0” and were never documented before. Yet they are extremely important for browser vendors to support existing Web content and for authors to be able to build Web applications.
