I think it was "dynamic instance". We had a discussion a while
back (ie. you explained it to me).

To clarify my answer to Zou: That proposal would be a no-op in our
test scenario.

It's not exactly clear to me what you mean, but also a PlaceObject2
tag that moves an existing instance should *not* re-initialize it, no
actions should be executed.
