In response to the increase in user interface (UI) complexity on the Web, the Web Accessibility Initiative World Wide Web link group has defined a roadmap for Accessible Rich Internet Applications (ARIA), which introduces ways for Web site authors to define how custom UI elements are accessed. ARIA accomplishes this by defining a set of HTML attributes that map back to common UI controls. As a result, users with disabilities can access Web sites with a rich interaction model. By exposing ARIA through the Microsoft Active Accessibility API in Internet Explorer 8, assistive technologies that already use Active Accessibility can also support ARIA easily.

The alt attribute is no longer displayed as the image tooltip when the browser is running in IE8 mode. Instead, the target of the longDesc attribute is used as the tooltip if present; otherwise, the title is displayed. The alt attribute is still used as the Active Accessibility name, and the title attribute is used as the fallback name only if alt is not present.

Pian piano Internet Explorer sta facendo progressi; apprezzabile no? Nel frattempo rimango fedele al mitico Firefox ;)
