Tests limited to few elements
The Worldwide Web Consortium (W3C) has published results from its first set of HTML5 compliance tests, which were topped by the latest Internet Explorer 9 beta. Microsoft's browser was found to adhere to a limited set of features more closely than Firefox 4 beta 6, Chrome 7, Opera 10.6, and Apple's Safari 5 browsers.
The W3C tests only covered seven features of HTML 5, including attributes, video, canvas, getElementsByClassName, foreigncontent and XHTML5. Omitted standards, however, included elements such as the file API, local storage, drag-and-drop, Web Workers, and SVG animations, among others.
As noted by Wired, IE9 appears to be up to speed with a few of the most common components in HTML5, but the browser would fall far behind its competition if the W3C had tested a wider range of elements. Aside from HTML5, IE9 also lacks support for many CSS3 features that can be viewed on Firefox, Chrome, and Safari.
Microsoft recently announced that it will shift its strategy to focus on HTML5 instead of its Silverlight for cross-platform endeavors. The company's PDC event showcased IE9 running HTML5 demos, including animations and video.
The final version of Internet Explorer 9 is expected to be released next year, while the HTML5 specifications may not be finalized for two to three years. [via The Register]
