I argued for an event back in the day but lost.  You shouldn't have to
customize an item editor to deal with the lifecycle of editing.  Events are
easier to hook up to, even if it is a bit less object-oriented.

Now, I see two options:  One is to modify DG to dispatch such an event.
Another is to provide an alternate item editor that dispatches the event
from the DG in its save() method.

In the new framework I am rewriting, I would argue for the second option.
The DG should not waste time dispatching events just-in-case.  You can turn
on that capability by choosing a new default renderer.

But for the legacy code base, we would probably choose option 1.
