Re: [xml-dev] Invalid attribute names

Spec 2.3 "Common Syntactic Constructs" says:

[4]  NameChar ::=  Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar | 
Extender
[5]  Name ::=  (Letter | '_' | ':') (NameChar)*

Colon and underscore are valid name start characters.
I believe parsers shouldn't report this as a well-formedness error.
