Prince doesn't support exception dictionaries. Is it not possible to
encode exceptions in the hyphenation dictionary?
DSSSL has an 'hyphenation-exceptions' property which takes a list of
strings. I'm unsure if it has been implemented, though.

This can be done by supplying your own dictionary through the

Prince6 does't try to go beyond Tex.
