Being able to do something like

<process-definition name='superprocess'>
<start-state name='start'>
<transition to='sub process state' />
</start-state>
<process-state name='sub process state'>
<sub-process name='#

' binding='late'/>
<transition to='wait' />
</process-state>
<state name='wait' />
</process-definition>

Would be great. This way you can have dynamic subprocesses based on e.g. a variable in the process....
