So, I just did this now on top, but it would seem better to do it
before the conversion, so I'll rebase and reorder the changes and
send an updated series tomorrow.

This should be fine now. :)

I've also now added a run for xmllint. Took also a look at replacing
dblatex with xmlroff, but it fails hard, and upstream also seems
stagnant, so abandoned that route.
