Ah now I think I now see what you mean. You're using direct entries
and need therefore no change to the transitions.
Point taken. I can change the example by adding another flag and
giving it to one of the CDLoaded-states and one of the non-CDLoaded
states, thus preventing the use of an outer state, eventhough it might
make the example slightly more difficult than I intended. I really
simply wanted to bring this new general concept.
