SCXML serialization / deserialization

Can we add a feature to serialize and deserialize scxml state machines? IMHO this is a very useful feature to capture the state of a system before shutting it down and to continue in the exact state when turning it back on. But that would require to load a previous saved state from file to initialize the state machine or saving an exiting state to a file as either a QByteArray or JSON or some other format.
