As far as I am aware the 'tests' that LilyPond runs are basically using 
itself to compile the tests in the regression during test-baseline (and 
of course when you make doc) and then doing the same thing again when 
running make check except you get a visual difference by comparing png 
outputs between the two.

This is why you need a human to check any obviously poor differences 
rather than some minor adjustment because of, say, some spacing change.

With xml we don't such visual tests so I think that only the fact that 
they get compiled without complaint during test-baseline and check is 
enough.

At least that is how I understand it.
