Comment:
The third paragraph under the canvas element write-up:

--
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. This content may be placed as content of the canvas element.
The contents of the canvas element, if any, are the element's fallback
content.
--

This is very unclear:

The author "must provide content" ... then "The contents of the canvas
element, if any, are the element's fallback content"


does their have to be content or not? I don't know how to demonstrate this
with sample html and code.
