Decide Node
A Decision node is a node that represents a control decision in the model. A decision node has one incoming Succession and one or multiple outgoing Successions. Any one of the actions connected to an outgoing succession can start after the action connected to the incoming succession has completed, which of the outgoing Succession starts is based on the guards placed on the outgoing successions.
