Re: XSD elementFormDefault="unqualified" destroys the benefits

Hi Roger,

Interesting :), I did not thought about putting local elements from 
other schema/namespace inside local elements from the main 
schema/namespace directly. I always thought about local elements as part 
of the content of a global element from the same schema - and probably 
the unqualified form makes sense only in this case (similar with 
attributes in no namespace, that are local to the element that contains 
them).

Best Regards,
George
