Hi Paniz,

Have you read the links that Joshue posted? Start there, and if anything
needs further clarification after that be sure to ping back with a
detailed question and I'm sure you will get a focused response.

Hi Jhon,

You told me that there is a lot of problem that has not been answered.

Which problems?

Hi Paniz,

As active members of the HTML5 Accessibility Task Force at the W3C,
Steve's response to you, as well as the links supplied to you by Joshue,
are the most accurate and current information available today. There are
no papers or more formalized documents at this time because, frankly, the
problem has not yet been solved properly. I can appreciate that this is
not what you want to hear, but it is today's reality.

If you have ideas or suggestions on how to improve things, I urge you to
participate within the Task Force and share those ideas with Steve and
Rich (Schwerdtfeger) and the other members of the Canvas sub-group who
have been actively working on this issue/problem for many, many months
now. Not only does all of the accessibility requirements need to be worked
out (the most recent work has been with screen magnifying software
developers AI, makers of ZoomText), but we also need to see support
implemented by the browsers: browsers who are waiting to see what exactly
needs to be implemented, which at this time is still being spec'ed out.
This is a very large task/problem.

Your enthusiasm for taking on this subject is appreciated, but I
respectfully suggest that working within the on-going effort, rather than
trying to start over again from the beginning, will prove more productive
in the long run. There are still many questions that have not been
answered. I urge you to read the links Josh supplied fully, and if you
want to contribute, please consider joining the W3C Task Force and start
participating on the Canvas conference calls and contributing via the
mailing list set up at the W3C. Your participation there *will* be

As an aside, *ANYONE* can become a member of the W3C Taskforce, it does
not require a special invitation, nor a wall full of degrees and diplomas.
It simply requires that you care, wish to contribute, and have some time
to give to the effort. While we are (hopefully) coming toward the end of a
heavy round of effort on HTML5, ongoing work at the W3C never stops, and
results and successes are achieved in large part due to volunteer effort
from around the globe. It's fun, interesting and completely satisfying
work effort, and well worth the time spent. Consider it.
