Guideline 1.3 SC

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?
