xs:key, why is validation passing when key value is not member of key reference?

Question

I am interested in defining a key constraint in my Xsd. It is my understanding that using xs:key should constrain the value used to a member of a referenced list of values.<

I guess you should use ValidationEventHandler :

settings.ValidationEventHandler += new ValidationEventHandler (ValidationCallBack);

private static void ValidationCallBack (object sender, ValidationEventArgs args) {}
