These platforms have advantages and challenges all their own where universal design is concerned, and in this chapter, we cover them.
Now that the Web has begun to act like software, web accessibility comprises software accessibility. While we might have expected from the head start we had with software design that loads of software accessibility documentation would be here waiting for us, sadly, that part has not come to pass. There is not a corpus of software accessibility best practices that we can rely on—no books that we can recommend, no WCAG-like list of checkpoints. So in this chapter, we offer a crash course in software accessibility as applied to Flex and Silverlight.
The software accessibility guidelines that do exist need a refresh based on changes in languages and devices. Even then, it would be very difficult for any set of guidelines to address everything you can do with software in such the way WCAG 1.0 can do with HTML, or WCAG 2.0 tries to do across web technologies.
