Dear working group,

I attempted to respond via the W3C online account but it only presented
Comment 327 for a response and seemed to be unable to process the submission
of my acknowledgment. Here is an email response instead.

Thank you for taking my comments into consideration. Here are my responses.

Comment #327:
Response accepted.

Comment #328:
Response not accepted.

Please clarify the following statement " The assistive technology should
assess, based on what is
controlling it whether to speak a polite area or notify the user that the
area has changed."

How is an assistive technology to make such a determination? Are you
suggesting that the type of element would determine the appropriate response
(such as, an edit box would announce the polite area change whereas a radio
button would simply notify a changed status)? I imagine that it would be
difficult, if not impossible, for software to make the appropriate
judgments. An appropriate announcement would be highly dependent on the
content being presented.

In regard to "Instead of providing the full search result as polite region,
it's
sometimes more appropriate to only announce meta information of the search
results. This has to be provided by the author.":
This may require adding content to the page that may not have been
originally present - such as "450 matches found" (the value is updated with
each character added by the user in the edit field). Is this what you
intended to convey?


Comment #329
Response accepted.
I think this will potentially suffer the same software limitations outlined
in Comment #328. I look forward to seeing the development.



Thank you, once again, for considering my comments.
