Re: Non-unique ID on its own not a failure of 1.3.1 ( LC-2985)

 Dear Jason Kiss ,

The Web Content Accessibility Guidelines Working Group has reviewed the
comments you sent [1] on the Last Call Working Draft [2] of the Techniques
for WCAG 2.0 published on 11 Sep 2014. Thank you for having taken the time
to review the document and to send us comments!

The Working Group's response to your comment is included below.

Please review it carefully and let us know by email at
public-comments-wcag20@w3.org if you agree with it or not before
12/24/2014. In case of disagreement, you are requested to provide a
specific solution for or a path to a consensus with the Working Group. If
such a consensus cannot be achieved, you will be given the opportunity to
raise a formal objection which will then be reviewed by the Director during
the transition of this document to the next stage in the W3C Recommendation
Track.

Thanks,

For the Web Content Accessibility Guidelines Working Group,

Your comment on :

Working Group Resolution (LC-2985):
The failure in question was problematic in the ways you describe and
redundant to other failures in others.  As a result the WG decided to
remove F17 entirely.

Failures resulting from missing relationships between specific elements as
a result of id attribute value issues are covered in other techniques.
