Hi Andi and Makoto,

I think Andi could be right - much of what we've been discussing may fall 
under GL 1.3.

GL 1.3 L 2 SC 1 (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.) could cover error information 
portrayed with colour and programmatically determinable emphasis.

For this to be true I think the following two things need to be satisfied:
1) that "variations in presentation of text" apply across perceivable units 
(because the presentation only varies from the form's previous presentation 
without errors identified)
2) we would have to be able to safely assume that form errors would be 
rendered to the user as a variation in the presentation of text (ie, the 
form wouldn't simply be presented to the user again, with no errors 
identified or highlighted). This would be a general usability issue and so 
may be safe to assume for the purpose of WCAG 2.

I think the issues Makoto raised would fall under general usability. But 
there may be some aspects to form error identification and instruction that 
have a specific impact on accessibility.
For example, where relevant, a linked list of the errors at the top of the 
form may aid screen reader users.
Does this mean we need a different SC?
