yes but 

either that's true, in which case it is OK for Ken to use them in
XSLT, except that it means his assumption that they never occur in XML
input is not valid, as other people may consent to use these characters
as well.

or it is not true, in which case Ken's assumption that they do not
appear in input documents is valid, but it means that he can't use them
in XSLT either.

So either way I don't think they should be used (even thought they work)
and using private use characters is safer (especially if you wander up
into the higher planes were there will be less legacy usage)
