The point I was making is that application profiles/usage scenarios
will likely enforce the desried restrictions *without* any changes to
the XML spec. I think that's reasonable.

This is a good idea.

Right. I have no problems with *profiles* like this being done. I do
not think they need to be part of the language specification.

Like the above, I agree. Profiling should be outside the language.

I have no problems with deprecating them, but disallowing them will
make life harder for people *using* XML.

Count me as disagreeing. I think we should *allow*, but not
*recommend* private use characters and surrogates. Think of them as
being implicit SDATA entities...

Most of the proposals I have seen are not really "font delivery",
though there is lot's of talk.

Yes. A standard mechanism for defining the semantics, properties, and
glyph/glyph image selection for characters needs to be built.
