Hi Cynthia,

I didn't claim that these methods cause accessibility problems. My 
point was that I and many others prefer to promote standards-based methods.

The introduction to the techniques document 
<http://www.w3.org/TR/WCAG20-TECHS/intro.html> does not explain what 
failing the test procedure in a technique means. We could add an 
explanation there. But users who come to a technique through 
"Understanding WCAG 2.0" or "How to Meet WCAG 2.0" will probably not 
see that explanation. Should we add something in the test section of 
the techniques?

Best regards,

Christophe
