I think this is a better approach.

I agree with this proposal, the list seems complete.

Yes please, even if it is quite clear that it should be the link to the formal specification.

This is one of the things that is convincing me to keep the techComment element (see the other thread of comments).

Is this definition of a "baseline with exceptions" really inline with WCAG 2.0?

We need more discussion about this model, I am not sure I understand the whole concept.

I vote for removing it because I don't see a use case for it in the context of this Task Force. I am happy to hear otherwise...
