Well, suppose I wanted to use a codepoint internally to a program for
some purpose or other -- for example, to indicate the point at which
a graphic was to be inserted in the final HTML output. If I allocated
U+E000 to that purpose, then that program could not be used to process
CSUR Tengwar text. Thus it is useful to have non-character codepoints,
which are not meant to be interchanged, as well as PUA codepoints,
which are meant to be interchanged under private agreements.
In essence, though not formally, U+FFF9..U+FFFC are non-characters as
well, and the Unicode "semantics" just tells what programs *may* find them
useful for. Unicode 4.0 editors: it might be a good idea to emphasize
the close relationship of this small repertoire with the non-characters.
