++ \section1 Connecting to States
++
++ In the SCXML file, we specify states for each light: red, yellow, and green.
++ In the \c <onentry> element, we specify the event to send when entering
++ the state and the delay in seconds before sending the event. In the
++ \c <transition> element, we specify the event that triggers the transition
++ to the state specified by the \c target attribute:
++
++ \quotefromfile trafficlight-qml-dynamic/statemachine.scxml
++ \skipto <state id="red">
++ \printuntil <state id="green">
++ \printuntil </state>
