NOTE 1 – A transition is enabled if all the immediately preceding steps, connected to this transition by directed links, are active.
NOTE 2 – A transition is cleared if it is enabled, and if its associated transition condition becomes true; this clearing then activates the following step, and deactivates the preceding step.
