For boostbook root xml files (like the one above) you'd also need to
check that the license appears in the <legalnotice> section.

That's quite a hard problem to solve, especially when a license can
appear in arbitrary places (like the XML comment as in the example
above). Except of course when you assume that all licenses have some
magic words in common.

I assume you suggest to keep checking the boostbook source xml only as
opposed to also/only check the generated HTML. While I agree with the
general statement, in this case, by checking the sources only, you
cannot detect when the doctools do something wrong. That's why I
suggested to check the generated HTML.

BTW, I do see that L & C checking is tricky business in general and can
never be made completely foolproof. All I'm saying is that the current
checks can be tightened with relatively little additional effort, either
by checking the presence and contents of <legalnotice> sections and/or
by checking the generated HTML. Then again, I don't know much about
boostbook or inspect so I could well be wrong.
