The purpose of global element is not to specify the possible root
elements, it just happens to be a side-effect. Global element declarations
affect other things such as substitution groups in XML-Schema.

In my opinion, this has always been one of the big defects with XML-Schema
-- want to do something, do something else -- and claim that you can do 10
different things..
