Lofton and Chris: I hope you can identify portions of your SVG test suite 
that address
accessibility for the WAI User Agent working group.

The User Agent Accessibility Guidelines seeks implementation experience 
supporting the
Web Content Accessibility Guidelines [WCAG1.0] that deal with image forms 
in SVG.
We would like to include examples from SVG. We also wish to include tests 
in the SVG
test suite that includes explicit tests for those WCAG1.0 requirements.

In my cursory examination of the SVG test suite I find no occurrence of 
"accessibility" in
any of the SVG html harness html files.

Do I assume that this was not a highlighted part of that test suite? Or do 
I assume that
the tests only indirectly address accessibility issues as part of different 

The Accessibility issues with SVG objects should be explicitly included, 
such as those identified in:

"Accessibility requires that the features offered by SVG are correctly used
and supported. This Note describes the SVG features that support accessibility
and illustrates their use with examples." ...
