Hi Rich,

Thanks for driving this.

I can't speak for Mozilla as a whole, but thinking of all our 
discussions and the feedback that has come from people inside and 
outside this group, this approach seems like a reasonable compromise to 
me, and I'd like to hear what others think.

Nits:

For the introductory paragraphs:

" When possible a facility must me" should be "be"

" accessible binding" needs to be defined. "Binding" might get confused 
with XBL etc.

" The determination of the disposition of the <canvas> subtree can be 
determined at load time." could be "can be done at load time."

" When set to true it indicates that the canvas subtree is to be use as 
a direct accessible subtree of canvas" could be " When set to true it 
indicates that the canvas subtree is to be used as a directly keyboard 
operable accessible subtree of canvas".

" The fallback content can come over the wire" could be "Progressive 
enhancement can be achieved since the fallback content...", and " a 
script can determine whether canvas is renderable" could be "a script 
can use feature detection to determine...".


In the proposed text for html5:

I would say something about the adom indicating that the sub-tree of 
canvas is intended to interact (be kept in sync?) with the canvas 
rendering. I would not prescribe that the " rendering of the subtree is 
controlled by script through the canvas API".

Regarding the last sentence " Add the following definition to the HTML 5 
glossary:" was there more here?

cheers,
David
