But if one accepted this claim, why would one prefer the shadow DOM tree approach to "canvas" interactivity over any other approach for providing equivalent information and functionality? The editor's draft already requires authors to provide this as a point of conformance: "When authors use the canvas element, they must also provide content that, when presented to the user, conveys essentially the same function or purpose as the bitmap canvas." http://dev.w3.org/html5/spec/Overview.html#the-canvas-element Given sufficient authorial effort, authors can conform by linking to an alternate version. For example, Bespin could link to a version of Bespin that does not use "canvas" for user interface. As long as correspondents do not compromise on the principle that authors must provide equivalent information and functionality as a point of conformance, why object when correspondents ask the WG to pursue approaches that deliver the same access with less authorial effort in the hopes that this will increase the amount of accessible web content? > how can we ensure accessibility to the Web? Except in so far as we bake it in to the technology people choose to use, we can't ensure it although we can and should encourage it. -- Benjamin Hawkes-Lewis
