Right;  the workflow system is "reactive", and needs to be notified that 
an object might need to transit.  E.g., imagine the case where your 
guard condition for the "expire" transition is "object.expired() < 
ZopeTime()".  Unless you trigger the workflow mechanism, the transition 
won't occur.

You could also arrange to trigger workflow transitions during your 
"edit" handling scripts;  this is what the old, now-deprecated 
WorkflowMethod wrapper did.
