English to Chinese Tech/Engineering IT (Information Technology) AJAX

As the latest browser war between Firefox and Internet Explorer heats up, AJAX developers need to be as agile and responsive as ever. There may be convergence on some issues such as CSS or XML, yet each browser camp has a different attitude towards adoption of the latest standards: Mozilla embraces the Scaling Vector Graphics (SVG) and ECMAScript for XML (E4X) standards as well as XML User Interface Language (XUL) in the latest beta version of Firefox. Microsoft stands by their Extensible Application Markup Language (XAML) technology. All of these technologies represent a marked change in direction from the current AJAX mainstays of JavaScript and XML.
