I do not see any problem in the schemas, Xerces 2.7.1 validates the
instance document without problems.
Note that xs:element/@name value is a non qualified name so it does not
require a default namespace and it is not allowed to specify a prefix;
the global elements belong to the schema target namespace.
Best Regards,
George
