Jack,
Thanks for the offer.
However, it's not clear to me how your solution solves my problem. Do you
suggest that _all_ UC realisations go in one seperate package? Where does
this package sit? In the Logical View? Above all sub-systems? That would
still mean that looking at a single sub-system, I cannot tell whether it
participates in the realisation of a use case.

Peter,
The problem is that you are skipping some of the details due to the design
decision. At the moment where you mention that class A and B go in two
separate subsystem, you have to "replace" the used analysis classes in the
use case by the interfaces of the earlier mentioned subsystems. The use case
realization will have it's own package, and in the sequence diagram it will
show the interface classes, not any more the classes A and B.
Classes should be relocated in the subsystem 'package' to which the belong.
In the package you will/should create sequence diagram, showing how the
subsystem internally works. To do so, you normally add an object
representing the outside world for the subsystem, making the call to the
subsystem. This should be an operation defined on the interface class. From
the 'dummy' object, you can so how the subsystem internally works, and how
your original class gets involved in it.
If you like, i can build and send you an example model on this....
Jack
