Re: Integration of HTM

Anne,

I disagree with this. Most people do not understand accessibility. However,
the author has the option of providing alternative content when the canvas
cannot be made directly accessible. To quote Apple, where possible the
author needs to work side by side with the sited user to use the same
application component.

I wholeheartedly agree. Making accessibility into something that only
consultants can do correctly would be a huge step backwards.
