Description

The SCXML spec defines a variable "_event" which is is bound to a structure containing the event name and payload:

_event.name
_event.data

The "_event" variable has to be read-only (from application point of view).

This change will break backward compatibility of existing SCXML documents. Would it be useful to keep the current variable "_eventdata" while adding the "_event" structure? "_eventdata" could be marked as depricated and removed later.
