Maintaning Objects in Mutiple Releases with OMW


Legendary Poster
We recently started with XE and are discovering/learning it now.
I have found a very interesting feature in Object Management Workbench which can be very useful for us, notably:
"Maintaning Objects in Multiple Software Release"
Has anyone experiences with this feature?
Does it mean, that can I use XE designers to modify objects under different release than XE?
Can I move an add-on development from e.g. B7331 into XE with this feature?
... and I have a lot of other question about this.
Any information will be very appreciated,

B7332 SP11, ESU 4116422, Intel NT4, SQL 7 SP1
(working with B7321, B7331, XE too)
