	Barbara,

  Thanks for checking.

  The list from ushyphex.tex isn’t used at all.  I’m surprised you
weren’t aware of that.  The list of patterns referred to as ushyphmax in
language.dat is Gerard Kuiken’s extension of hyphen.tex with extra
*patterns* but actually no new hyphenation exceptions.  I don’t know if
Dr. Kuiken had a specific reason to not extend his file with the
hyphenation exceptions from ushyphex; possibly because exceptions do not
actually need to be dumped into the format and can thus be loaded at
runtime.

  That was, at least, the situation as we found it ten years ago when we
took over the technical side of hyphenation patterns with Mojca.
Obviously we didn’t want to change the actual patterns and exceptions
without someone explicitly instructing us to do so; and for most major
languages, it turned out, the patterns were essentially abandoned with
no one maintaining them (again, contentwise); two exceptions are German
and Spanish, handled in two different ways in hyph-utf8.

	Best,
