Well I have a general tendency towards being liberal in these matters (as I've said before allowing nonsense is *sometimes* a good way to ensure you allow edge cases) so I can see where objectors would be coming from.

Hmm. To my mind that isn't uniform at all - someone familiar with Unicode would have already disallowed, say U+4FFFE, as a non-character before they got as far as the production (making it effectively excluded) where someone else relying on the XML spec for information about character properties would allow it.
Maybe CharMod will safe us all...
