Chris asked: <blockquote> Allan, J., and Slatin, J. (2005). Proactive accommodation: Web accessibility in the classroom. In D. Edyburn, K. Higgins, and R. Boone. (Eds.), Handbook of special education technology research and practice. (pp. 137-160). Whitefish Bay, WI: Knowledge by Design. </blockquote> Chris, in my opinion that's right-- for this specific success criterion taken in isolation. But remember that the guidelines and success criteria interact with each other. For example, at level 2 there is a requirement that would affect the alt text for a graphical link. Guideline 3.1 L2 SC6 says: <blockquote> 6. The destination of each link is identified through words or phrases that either occur in the link or can be programmatically determined. [V] </blockquote> As I recall, you've actually developed test files that take account of this sort of interaction among success criteria that appear under different guidelines. Of course the WCAG 1.0 guidelines and chekcpoints interact with each other, to. But we've grown accustomed to those interactions and they've become at least semi-transparent to us-- we've internalized them. Now we have to get used to teasing out the way WCAG 2.0 guidelines and success criteria interact with each other, and *when* they interact-- in the example above, the interaction between 1.1 and 3.2 occurs at level 2 but not at leavel 2 but not at level 1. Hmmm, maybe we need a visual representation to show this sort of interaction throughout WCAG 2.0-- another map. John "Good design is accessible design."

Is that right? Chris
