[Mono-dev] Mono & .Net difference - handling xs:extension please help

[Atsushi Eno]

Hello,

If you believe xs:complexType/xs:extension is that superficial, could 
you explain why the validation result is wrong?

Dealing with xs:complexType is one of the most complicated XML schema 
validation technology, which involved handful of ambiguity, which may be 
fixed in later specifications, after we have implemented this feature 
mostly in 2003-2004.
