Hi Wayne

see my comments on this in the other thread on focus contrast (just posted) 

Good luck

It would be a shift for WCAG WG members who do not recognize color and text level presentation as being capable of interfering with information, relationships,  structures or correct reading sequence.  The simple fact is that rigid content structures that prevent reasonable change to these parameters are the largest single obstetrical to visual access for people with low vision.  The link below gives the text of my second comments to the Access Board. I am proposing these changes.  The Access Board can adopt them as additional with no change to WCAG 2.0. Should the W3C decide the to change  the Techniques document everything can stay in total harmony.
