            appender.copyAndAppend(f, NEXT);
            if (f != l) {
                appender.copyAndAppend(f.getNextSemanticRegion(), l.getPreviousSemanticRegion());
            }
            appender.copyAndAppend(l, PREVIOUS);

        }
        last = rw.originalLast;
    }
    appender.copyAndAppend(root.getNextHiddenRegion(), NEXT);
    StringBasedTextRegionAccessDiff result = appender.finish();
    AbstractEObjectRegion newRoot = result.regionForEObject(root.getSemanticElement());
    result.setRootEObject(newRoot);
    return result;
}
