Hi Michael I think that is too narrow. You could have content provided over content and you would have the same problem. Foreground Content: Content that is presented in front of or on top of other content. Background: Anything that appears under foreground content. This could be decorative material or meaningful content. Also, I THINK we want to restrict the success criteria to text over a background, at least at the upper levels. Would be good to keep it general - but I think we should focus on text over a background for our primary guidelines.

We weren't sure that the definition of "foreground" and "background" was clear enough for us to write techniques to. Is foreground text and background everything else? Can an image be foreground or background, and if so what's the rule for determining when it's which? What if there is text in a background image? We need a definition for these terms in the guidelines. A starting proposal: Foreground: primary content intended for the user. Background: decorative or ancillary visual elements that is co-presented with foreground content, with the background generally appearing "behind" the foreground, but not itself part of the semantic content of the page.
