If a user renders a given .fo file on two different systems, using the same renderer (say, PDF), and specifies a font family (say, Baskerville) that does not exist on the first system, but does on the second, what result should be expected?
If the user specified a fallback, it is tried, otherwise I'd expect an error abort. What should be the alternative to the latter? Guessing the font characteristics and using a substitute font?
