XmlSchema code generation: Output C# code to multiple namespaces

For anyone who has utilised classes under XSD.exe and CodeDOM (please
redirect me to another group perhaps if not here) please any ideas on how to
translate the multiple namespaces present within multiple XmlSchema , i.e.,
via xs:import, to multiple output C# namespaces when using CodeDOM?

Have no problem passing multiple schemas to XmlSchemaImporter and generating
to single namespace, but this is pretty useless in any moderately complex
enterprise where multiple assemblies are being shared which by design will
have distinct namespaces. This is also an issue with WSDL, all classes end up
in one ns
