## Typedef Documentation

### ScXMLStateChangeCB

This callback type is for notifying listeners on when the state machine enters and exits states that are tagged as 'tasks' for logging purposes. This is what the Boolean 'task' attribute in the state element sets up.

The *success* argument is currently unsupported (will always be TRUE), but has been preemptively added to avoid a signature change later.
