Michael,
With incomming tokens I do not mean incomming transitions.
Suppose a fork splits of two tokens T1 and T2. Each of which goes to a
descision (T1 to D1 and T2 to D2) which in turn have two transitions to tasks
(1A, 1B and 2A, 2B). So either 1A or 1B AND 2A or 2B are taken. Below this
btw, your question about child tokens could be related to
