Sorry this takes you by surprise, and with a negative response. We
think it's a _very_ important property of XML Schema that it builds on
_top_ of XML 1.0 plus Namespaces, and starts where they leave off,
rather than starting all over again at the level of BNFs for character
sequences. Providing the latter would have _considerably_ increased
the size of an already large spec.
