An attribute declared in a particular schema document will either be in no
namespace, or in the targetNamespace of that schema document (depending on
form/attributeFormDefault). If you want it in a different namespace, you
should create a schema document with that as the targetNamespace, declare it
as a global attribute declaration, import that schema document into the one
where the element is declared, and then reference it from the type
definition using <xs:attribute ref="ns:att"/>.
