No, in this particular scenario I'd leave all the existing transitions in place and just add the CDLoaded outer state. This is barely more work than adding the flag, right? Ultimately, what I'm getting at is that your justifying example in MsmSession_Handout.pdf could be better, because most Statechart users wouldn't write the code you're implying they would. MSM vs. Statechart aside, MSM users might be left with the question what flags are good for when they can achieve the same with an additional outer state. Again, flags are good, but the justifying example isn't.

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. Regards, Christophe
