done.state.* events are internal. You can expose them using this snippet of scxml:

<transition event="done.state.*" cond="_event.type === 'internal'">
     <send eventexpr="_event.name">
         <param name="value" expr="_event.data.value"/>
     </send>
</transition>

It requires the ecmascript data model and knowledge of the possible parameters, though. Also, <donedata> is sent with the done.state event of the parent state, not the done.state event for the <final> itself. That is, you want to listen for done.state.<Leave's parent> here, not done.state.Leave.

(I'm just realizing that the ftpclient example that comes with 5.8 is actually invalid scxml. If it wasn't, it would be a great example for how to forward events. So, don't look at it until it's fixed.)
