I don't agree, Chris.   I would say that alt text for a graphical link
conforms at level 2 if it satisfis both 1.1 L1 SC1 *and* 3.2 L2 SC2.

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.
