For conformance, there's no dependence on other software. There are
only three possibilities for a checkpoint: you satisfy, you don't, or
it's not applicable. There's no option for "done by other software".

It may be that ATs do some tasks better, and general UAs have to
make information available to them. But a tool's conformance must
be independent of other tools.
