If a DecisionNode has a decisionInputFlow, then a token must be offered on both the primary incoming edge and the decisionInputFlow before the token from the primary incoming edge is offered to the outgoing edges. If the DecisionNode does not have a decisionInput, then the value contained in the object token on the decisionInputFlow is made available to the guards on each outgoing edge, regardless of whether the primary incoming flow is a ControlFlow or an ObjectFl Visit also Visit also (backlinks) Flags
