From what Ken says, it sounds like it will be wrong from whenever
Unicode 4.0 is officially issued because this paragraph has been
excised from that standard. But until then it seems to be correct, SPACE
is indeed "considered a format character". I was misled by Jim's
reference to the URL of the final draft (as clearly stamped on the first
page) of 4.0, but since in fact he was quoting from 3.0 what he says can
hardly be considered obsolete yet.
