No, that's not what I want. I was perhaps too brief when I wrote

"I'd like the markup validation service to provide clear feedback
about that problem."

Oh please! I made it pretty clear that I am an actual user of
the validation service, and I was using it in my real-world, day-to-day
life, maintaing pages for groups that I serve, and in the course
of doing so, the output of the validator surprised me.

Only because I haven't found time to capture the situation in a separate
test file. Do you guys maintain regression tests somewhere?

Pressing or not, it's useful to report problems as I find them, no?

More on that after I've had some time to think it over, I hope.
