Mark pointed out that we have a similar note in
F38<http://www.w3.org/WAI/GL/WCAG20-TECHS/F38.html>and
F39 <http://www.w3.org/WAI/GL/WCAG20-TECHS/F39.html>, and by the reasoning
that led to the resolution of Issue
LC-2723<https://www.w3.org/2002/09/wbs/35422/20130117misc/results#x2723>,
we plan to remove the note from those failures as well. Please let us know
if you have any objection to this.

There is still an open issue on how to update
F30<http://www.w3.org/WAI/GL/WCAG20-TECHS/F30.html>
.

Loretta
