Hi,

This solution is fine because it eventually achieves the same thing:
Make the user aware of his/her mistake. And on the other hand: The
compiler errors aren't always that enlightening either. (Try to make a
mistake in the transition table for example, you'll hit the "error
motherload" soon enough ;) )

I was confused by the fact that "event6" also triggered a normal
transition. Also, in the diagram, the arrows from Substate3 to
PseudoExit1 and from PseudoExit1 to State2 both have "event5" as text,
but I think it is more consistent when the second arrow has "event6".
I really admire the fact that the documentation has such a high value
for you guys, other projects should really take this as an example.
Great work! Keep it up!

Best regards,
Johan
