Re: Proposal for moving COGA SC forward

Sorry, I thought we were talking about a separate document?

One sitting alongside WCAG 2.1 for the best practice advice that doesn't fit the SC model.

If I understand your proposal, I think it's a more radical change to the
guidelines structure than we'd want to do in a dot-release to WCAG 2.0.
As a dot-release, I think we need to stick with the principles -
guidelines - success criteria model, or it won't be sufficiently
backwards compatible with WCAG 2.0. That does indeed create constraints,
and is one reason WCAG 2.1 should be viewed as an interim release, not a
"solve all the problems" version. I'm almost positive we'll want a
different structure in future guidelines, which is what the Silver task
force is working on.

My thoughts on cognitive accessibility "pillars" admittedly "shoe-horns"
them into the SC model. It's not perfect, but it's an attempt to get
some progress in 2.1, within its structure, with the expectation that
we'll be able to do better in later guidelines releases.
