Comment:
"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." While everyone can probably agree that alternative
content is a good idea when feasible, when considering what people are using
the canvas for, which seems to fit the examples provided in the first
paragraph well, the wording "they must" doesn't make any sense to me. How on
earth do you expect authors to provide alternative content for a game or a
complex visualization? I suggest either softening the first sentence up or
just whacking it entirely. Otherwise thanks for a nice and clear spec. :)
