         The config element is the top-level element for an .xsdconfig file.
         It contains configuration information that guides the xsd compiler
         when it generates Java classes. You can specify package names to
         be used for whole xml namespaces; you can specify class names
         to use for individual schema types; and you can supply extension
         interfaces and implementations to be extended by the generated
         Java classes.
