: Once this is fixed, the next step to update the references is actually not that bad according to what is being done XSD's ''UpdateNamespaceInformationCommand''. What XSD does is it calls ''schema.updateElement()'' and that will update all the references magically. I'm assuming it does some magic with resolving the prefix/namespaces. The same type of call would need to be made in ''W11EditNamespacesCommand'' for the definition object. (See ''UpdateNamespaceInformationCommand#updateElement()'' for more details).
