I would like to have all user agent developers to please provide
feedback/changes they would like to see made to the proposal by Monday so
that I may make any necessary changes to the final draft for May 24, 2010
to submit for a straw pole vote on May 27 in the HTML accessibility task
force.

Frank Olivier is going through the proposal with a fine tooth comb and will
submit feedback on Thursday in terms of how these changes will map to the
Windows accessibility API. These simple changes can all be made in MSAA as
I see it so they will also be applicable to Firefox. That said, I would
like both David and Alex to review the comments from Frank and submit them
to the list. There seems to be a gap on Linux that we may need to fill. I
am not aware of an ATK API to have a magnifier track the caret screen
position. This may need to be added.

As for Apple I would ask Maciej to look the changes and say if it can be
mapped in some way to the Mac OSX accessibility protocol either now or in
the future and if there are any changes that need to be made to the
proposal. I plan on wrapping this up next week.

Frank indicated that the HTML working group may wish to tweak the API or
API parameter names. Personally, that is not an issue for me as long as
they are well documented which given the feedback I have as of today the
changes made the API modifications clearer. Changes reside between <ZZ> and
</ZZ>

I know the HTML working group would like to wrap this all up quickly so I
urge you all to review and provide feedback in the requested time frame.
Here is the proposal with the attached changes in HTML format:

There will be no Canvas Accessibility API meeting on Monday, May 17, 2010
as I am traveling but I will have access to email and look forward to your
feedback.

Best Regards,
Rich
