In reviewing the criterion for guideline 1.3, I think there are a couple of issues we should try to address before the next public draft. <current> L1 SC2 - Information that is conveyed by color is also conveyed when color is not available, or can be programmatically determined. L2 SC1 - Information that is conveyed by variations in presentation of text is also conveyed when variations in presentation of text are not available, or can be programmatically determined. </current> Grammatically, both of these are problematic because it is not clear what can be programmatically determined. Here are a couple of proposals to address this: <proposal 1> L1 SC2 - Information that is conveyed by color is also conveyed when color is not available, or color information can be programmatically determined. L2 SC1 - Information that is conveyed by variations in presentation of text is also conveyed when variations in presentation of text are not available, or the presence of the variation in presentation can be programmatically determined. </proposal 1> <proposal 2> L1 SC2 Information that is conveyed through color is also conveyed through text or the color coding can be programmatically determined. L2 SC1 Information that is conveyed by variations in presentation of text is also conveyed in text or the variations in presentation of text can be programmatically determined. </proposal 2> Also, Level 2 SC2 still reads, "Any information that is conveyed through color is visually evident without having to interpret color. For example, the distinction can additionally be determined through context, characters, or symbols that accompany the color presentation, or through pattern differences such as dotted red vs. solid green lines in a graph." Seems like this should be reworded to match the changes in the L1 SC. One proposal was to simplify this to say, "Information that is conveyed by color is also conveyed when color is not available" but this wording would allow markup alone to meet the criterion, making it no more restrictive than the level 1 criterion. So, how about: <proposed> Any information that is conveyed through ccolor is visually evident when color is not available. </proposed> Thoughts? -Ben -- Ben Caldwell | <caldwell@trace.wisc.edu> Trace Research and Development Center <http://trace.wisc.edu
