I thought PUA characters had very specific meanings, defined by the
private parties who assign them, but utterly ignored by the standard.

What Philippe may have meant by "semi-private characters" is "characters
whose privately assigned meanings have been publicized." This would
include CSUR scripts, Apple's and Microsoft's assorted ligatures and
dingbats, and William Overington's stuff.
