Somewhere it says that the derived property files are subservient to the
other files. And in fact in some Unicode releases, they contained
errors. I therefor changed my parser to populate my internal db first
with the derived files, and then to populate using the non-derived
files. Any conflicts were thus automatically resolved in favor of the
non-derived. But if the derived files contained things not in the
non-derived ones, they would be used.
I think that Unicode is doing a better job of making their files
consistent and accurate these days, but I haven't had to worry since I
made that change. (I no longer remember any details of what the
problems were.)
If I were starting from scratch, I would try the xml version first.
