Dear Olivier,

Thank you for your comments on the 30 June 2005 Working Draft of WCAG
2.0. I've added your comments script techniques to our issues database.

<http://trace.wisc.edu/bugzilla_wcag/show_bug.cgi?id=1751>

If you have any questions about the issues list interface, please let us 
know.

Thank you for your patience while the WCAG WG responds to the variety
of comments we received on this last Working Draft.

All the best,

-Ben
