/*
 [4]  NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar | Extender
 [5]  Name ::= (Letter | '_' | ':') (NameChar)*
 [7]  Nmtoken ::= (NameChar)+
 [84] Letter ::= BaseChar | Ideographic

 We don't do this quite right; we rely on the Unicode charsets to do this analysis.  While
 the productions in the XML spec are based on the Unicode character sets, the definitions
 differ slightly to avoid those areas where the Unicode standard is still being resolved.
 At any rate, I'd lay money that using the Unicode charsets, we will be more correct than
 the vast majority of parsers out there.

 Letter == kCFUniCharLetterCharacterSet
 Digit == kCFUniCharDecimalDigitCharacterSet
 CombiningChar == kCFUniCharNonBaseCharacterSet
 Extender - complex, and not represented by a uniform character set.
