Response to your comments on WAI-ARIA 1.0 User Agent Implementation Guide

Dear Matthew King:

Thank you for your comments on the 10 January 2012 Last Call Working Draft
of WAI-ARIA 1.0 User Agent Implementation Guide
(http://www.w3.org/TR/2012/WD-wai-aria-implementation-20120110/). The
Protocols and Formats Working Group has reviewed all comments received on
the draft. We would like to know whether we have understood your comments
correctly and whether you are satisfied with our resolutions.

Please review our resolutions for the following comments, and reply to us
by 21 September 2012 to say whether you accept them or to discuss
additional concerns you have with our response. If we do not hear from you
by that date, we will mark your comment as "no response" and close it. If
you need more time to consider your acknowledgement, please let us know. 

We have sent this response shortly before publishing a planned updated
draft of the WAI-ARIA 1.0 User Agent Implementation Guide. This document is
being returned to ordinary Working Draft because the group found
ambiguities in user agent implementation expectations. If your concerns are
still open in this document, you may submit a new comment on that version
in addition to acknowledging our response to your prior comment. The group
intends to respond to all known issues and then publish a second Last Call
Working Draft.

You can respond in the following ways:

* If you have a W3C account, we request that you respond online at
http://www.w3.org/WAI/PF/comments/acknowledge?document_version_id=18;

* Else, by email to public-pfwg-comments@w3.org (be sure to reference our
comment ID so we can track your response). Note that this list is publicly
archived.

Please see below for the text of comments that you submitted and our
resolutions to your comments. 

Note that if you still strongly disagree with our resolution on an issue,
you have the opportunity to file a formal objection (according to 3.3.2 of
the W3C Process, at
http://www.w3.org/2005/10/Process-20051014/policies.html#WGArchiveMinorityViews)
to public-pfwg-comments@w3.org. Formal objections will be reviewed during
the candidate recommendation transition meeting with the W3C Director,
unless we can come to agreement with you on a resolution in advance of the
meeting.

Thank you for your time reviewing and sending comments. Though we cannot
always do exactly what each commenter requests, all of the comments are
valuable to the development of WAI-ARIA 1.0 User Agent Implementation
Guide.

Regards,

Janina Sajka, PFWG Chair

Comment 361: Accessibility tree inclusion conditions may need to address css visibility
Date: 2012-02-06
Archived at: UNSET
Relates to: WAI-ARIA 1.0 User Agent Implementation Guide - 5.1.1. Including Elements in the Accessibility Tree <http://www.w3.org/TR/2012/WD-wai-aria-implementation-20120110/#include_elements>
Status: Accepted proposal

-------------
Your comment:
-------------
Some browsers do not include elements in the accessibility tree if content
is hidden with display:none or visibility:hidden. It is debatable, at least
for aria-describedby, whether this is desirable behavior. Currently,
section 5.1.1 prescribes that hidden elements that meet the other
conditions listed need to be in the tree, which is different from current
browser behavior. Either browser developers need to agree to the prescribed
behavior or the prescription of this section needs to be modified.

--------------------------------
Response from the Working Group:
--------------------------------
We agree this is an issue. We will be incorporating the Hidden definition
in the ARIA 1.0 specification into the UAIG. We will be revising section
5.1.1 to state that Hidden elements SHOULD NOT be exposed to the
accessibility API. We are tracking this as action 968.
