It indeed sounds reasonable, we have a little bit different needs than
LaTeX 3, where  they test only the log file, but with all three main
engines. We need to test several files for each tested file (at least
the XML and CSS), we also need to be able to pass different options
for particular tests. I haven't read l3build documentation and source
code yet, so I have no idea how difficult it will be to get that to
work. But I am sure that it can't be harder than to start from

Best regards,
