I had a similar challenge some years back. I met it with schematron.

Write a 2nd stylesheet that generates schematron rules describing the 
expected structure and content of the output files. Run these against 
the output.

Of course there is a risk that your schematron rules will be incomplete 
in the same or different manner than your transformation stylesheet. But 
they will be able to check for known errors, such as the one you have 
already discovered.
