Re: [xml-dev] Your XML documents may use different sets ofcharacters, depending on which implementer you select?

Neither XML 1.0 nor XML 1.1 says any such thing.  Both of them specify
a that almost all Unicode characters can be used in XML documents, the
exceptions being most control characters (in 1.0) and just NUL (in 1.1).

> The XML specification mandates version 2.0 of Unicode.

No.  Editions 1-4 of XML 1.0 allowed only a fixed list of XML characters
to be used *in names*, a list based on the general categories of Unicode
2.0.  The current 5th edition, as well as XML 1.1, allow almost all
characters in names with specified exclusions that are not based on
general categories.

There are three kinds of people in the world:   John Cowan
those who can count,                            cowan@ccil.org
and those who can't.
