Re: Deep Dive on WCAG 3.0 Conformance August 11th

Dear Rachael, all,

Great to see this coming along!

I'm out of the office on August 11 but will try to attend. I responded 
to the two surveys and am adding some further thoughts below. However, 
as I've not been involved in most of the discussions, please feel free 
to dismiss my comments if they are rehashing past decisions or if they 
are otherwise less helpful to the group.

As to my thought, I strongly welcome that both approaches try to build 
on ACT Rules and atomic building blocks! I definitely think there is a 
lot of merit in such a test-driven approach for defining requirements. 
However, the downside is that the current ACT Rules are based on WCAG2 
requirements, which tend to be quite broad in nature (eg. SC 1.3.1).

Most testing methodologies I know break down the WCAG2 requirements in 
smaller and more contextualized sub-requirements. For example, even SC 
1.1.1 would be typically broken into something like these situations:
  * Informative images
  * Complex images
  * Decorative images
  * Images of text
  * Functional images
  * Controls
  * ...

 From John Foliot's slides (especially slide 3), it seems he is already 
suggesting that in addition to assigning relative points to each item.

Breaking down the requirements in such a way would make WCAG3 a longer 
document but in my view likely clearer and easier to follow. It would 
also allow more granular scoring and differentiation of severity (ie. 
text alternatives on decorative images may be scored differently than 
complex images). Some WCAG2 requirements are already quite granular.

Note: for situations where there is no matching sub-requirement, the 
parent requirement could be used. For example, in the illustration of 
1.1.1 above, CAPTCHAs and other situations not currently considered 
could be treated as generic "non-text content" as currently in WCAG2.

Best,
   Shadi
