Re: XML 1.0 5th Ed. PER: Unicode upgrade

Hi Henry,

I have no objection.
It seemed it would be relatively easy to "future proof" more generally 
than by using Unicode 5, but if the working group is satisfied with the 
amount of future proofing in the current change, then so am I.  Thanks for 
considering my issue.

Thank you for your observations about the proposed 5th edition of XML
1.0, which the XML Core WG have considered.  We have decided not to
make any changes, however, as we think the spec. already does what you
suggest: the Char production [1] already allows almost all the 16-bit
codepoints, all the (mostly unused) 17--20 -bit code points and the
first 65K 21-bit codepoints (again, currently unused).  One is advised
to 'Never say never', but let us say it is extremely unlikely that we
will ever need more than 17 times as many characters as we are
currently using, so this really does seem sufficient for the
indefinite future.

Please let us know if you are content with this resolution.
