Actually, I believe this applies to almost all the SC. You can put them at
whatever level you like and their requirement is still the same.

I think we need to allow for multiple levels of conformance and the current
scheme doesn't support that. There's no way to allow for (using my earlier
example) level 1 conforming alt text and level 2 conforming alt text.

That's why I'm suggesting that the conformance level for
techniques/tests/checklists be set at the technology specific layer. Let
each technology that has conformance documentation set its own conformance
level. It would be much simpler and easier and bound to be more accurate.

Is there a problem with moving the conformance level down to the technology
specific layer? I don't think it would have much of an impact on the WCAG
document itself. General conformance stuff stays in the WCAG while specific
conformance stuff goes in the technology specific layer.
