If that's the case, then that's great.  As a paranoid Debian package
maintainer, I'd prefer it if upstream would include a copy of the license
granted by the font company.

Of course, that free to use and distribute is not sufficient for Debian
main.  They would also have to grant a license to create derivative works
and distribute those derivative works, including the derivative work of
extracting the fonts and distributing them alone.  That's why I'd like to
see the original font license so that it's possible to verify that the
correct rights are granted.

If that isn't possible, I think it's kind of a murky area.  I'm not sure
I'd support going on a crusade against such documents, but I'd much rather
see all documents in Debian have a clear provenance, including being built
from fonts in Debian.

(Full disclosure: one of my packages has PDF files with no source because
the source has been lost and not even upstream has anything but pure PDF
files.  I gave it a lot of thought before including them.  They're the
only available documentation of certain protocol issues, so they're
useful, but I'm still not clear on whether they're really DFSG-happy.)
