 Response from the Working Group

Thank you, we have updated the test procedure to clarify these issues. See
http://www.w3.org/WAI/GL/WCAG20/WD-WCAG20-TECHS/H45.html .

Could you let us know by Monday, December 8 whether you are satisfied with
our resolution? If that date is not possible, please reply to this message
indicating when you will be able to respond.

If we do not hear from you by Monday, December 8, we will assume that you
are satisfied with the responses to your comments.

Thanks again for the interest that you have taken in these guidelines.
