+Scenario: Root element {{{A}}} contains element {{{B}}} and element {{{C}}}.  Element {{{C}}} is to be saved in a separate domain file.
+
+Solution:
+  - Create an element {{{CReference}}}.
+  - {{{CReference}}} contains an element {{{C}}} with {{{containment=false}}}.
+  - Override method {{{doDefaultElementCreation()}}} in class {{{CReferenceCreateCommand}}}. This method contains the creation of the corresponding element {{{C}}}, similar to the following:
+{{{
+// create CReference-Object
+EObject cReference = super.doDefaultElementCreation();
+
+// get resource of root element A
+Resource aResource = getElementToEdit().eResource();
+
+// create C object
+C c = ExampleFactory.eINSTANCE.createC();
+
+// add c to cReference
+((CReference)cReference).setC(c);
+
+// create model file for C
+File cFile = new File(pathToCFile);
+if (!cFile.exists())
+   try {
+        cFile.createNewFile();
+   } catch (IOException e) {
+        // TODO Auto-generated catch block
+        e.printStackTrace();
+   }
+
+// create resource for c
+Resource cResource = aResource.getResourceSet().createResource(
+        URI.createFileURI(cFile.getAbsolutePath()));
+
+// add c to new cResource
+cResource.getContents().add(c);
+
+// save resource; this will also be done by the save command of the generated editor unless you reduce the save command
+try {
+   cResource.save(ExampleDiagramEditorUtil.getSaveOptions());
+} catch (IOException e) {
+   // TODO Auto-generated catch block
+   e.printStackTrace();
+}
+}}}
