Hello Loretta,

You have completely lost me with this matter.  I was talking about
amendments with sufficient techniques G156, C23 and C25 which are all in SC
1.4.8 and deal specifically with colours and what happens in various user
agents.

You're replied with use of multiple sufficient techniques and given an
example of SC 2.2.1 stating AND for sufficient techniques.

To me the two things are completely different as I was trying to make
amendments within specific sufficient techniques, not stating that there
needed to be more than one sufficient technique, or have I missed the point?

Sheena

 I also wrote C25 and while the user agent notes are not added to this,
reference to the issues is made within the text.

Firefox have corrected the following issue (NB I'm not sure about
Netscape.) - 'When specified colors are overridden in Firefox and Netscape,
most Javascript pop-up boxes and drop-down menus become unusable. Pop-up
boxes gain a transparent background, superimposing the text of the box on
the text of the page, and drop-down menus either become transparent or gain
a dark-grey background.'

================================
Response from the Working Group
================================
Thank you for bringing this to our attention.  We are simplifying the
paragraph and providing an example:

Sufficient techniques are provided in a numbered list where each list
item provides the technique or combination of techniques that can be
used to meet the Success Criterion. When there are multiple techniques
on a numbered list item connected by "AND" then all of the techniques
must be used.

For example, Situation B in Understanding Success Criterion 2.2.1
lists as the third sufficient technique:
  SCR16: Providing a script that warns the user a time limit is about
to expire (Scripting) AND  SCR1: Allowing the user to extend the
default time limit  (Scripting)

So both SCR16 and SCR1 must be used to satisfy this success criterion.
