Using this option with the resource that really contains some ancestor.
/**
* Write only the subtree starting at the specified list of EObjects,
* which must be objects contained by the resource.
*/
String OPTION_ROOT_OBJECTS = "ROOT_OBJECTS";

Otto,
So you need something that doesn't reflect the real (complete) state of
the objects. That's not so easy. You'd need to specialize XMLSaveImpl
for stuff like that.
