Hi Ed,
This is definitely a bug. The [out] direction is enforced old objects to
be discarded. Could you please raise bugzilla for that?

Hi Sergey
(Bug 320010 raised for the rerun causing append.)
Now I want to execute in update mode. Is this supported?
(OMG QVT Issue raised on the very opaque and contradictory definitions
of "enforce", "checkonly" and MappingOperation.refinement.)
Regards
