["Kenn Hussey" <khussey@xxxxxxxxxx>]

Peter,

You'll need to use the UML resource implementation instead of the default 
XMI one if you want the serialization to look as expected. That is, as 
outlined in the FAQ (see 
http://wiki.eclipse.org/index.php/MDT-UML2-UML-FAQ#What.27s_required_to_load_a_UML_.28.uml.29_resource_from_a_standalone_application.3F), 
you'll need to register the UML resource factory like this:

resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, 
UMLResource.Factory.INSTANCE);

There are several threads in the old newgroup (eclipse.tools.uml2) on the 
subject of parsing XMI files as UML... try searching for "XMI2UML".
