They do (although some difficult pango or fontconfig bug (#403914) can
give us some "surprises" when chosing the font family).

 [made-of::data:postscript]

OK.

Right, it just doesn't say which kind of font we have.

Well, when looking for fonts for writing TeX documents, I usually look
for Type1 fonts because they are:
  - good for PDF files (as opposed to MetaFont fonts)
  - in general easy to use with TeX (as opposed to TrueType fonts, which
    are usually more tricky to make work with TeX).

But if you think so, I can admit this is too rare a need to warrant new
tags.

Yes (and I maybe truetype would imply opentype, because ISTR that
opentype is a superset of truetype, but I'd have to ask an expert to be
sure this is always correct...).

OK.

I think this is a difficult problem, because sometimes, a given font
only covers some parts of a script...

If the number of fonts in the archive is more or less manageable for the
users (which may well be), then maybe this is not worth the trouble.

Thanks for your anwser.
