Russ,

Of the issues I noticed, that is the least important, so, if you are
convinced it is ok, let it go.

That said, I didn't believe the definition was obvious in the
particular context I mentioned, finding that sentence in the Unicode
17.0 document is not easy unless one is looking for/at the change
list, and there has been confusion about the issue within Unicode
contexts.  But, again, I do not feel at all strongly about this.

best,
   john
