HTML 5 is the main focus of the WHATWG community and also that of the (new) W3C HTML Working Group. HTML 5 is a new version of HTML 4.01 and XHTML 1.0 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. These APIs are known to some as “DOM Level 0” and have never been documented. Yet they are extremely important for browser vendors to support existing Web content and for authors to be able to build Web applications.
