Hi, Philippe,
These are two completely different things. An ExpansionRegion is a
kind of structured node in an Activity. A CombinedFragment is kind of
fragment of an Interaction. It would never be present in an activity.
The Papyrus sequence diagram editor does provide a tool for creation of
combined fragments.

Hi, Philippe,
That feels to me like a good case for the ExpansionNode, which
naturally maps inputs to corresponding outputs. The LoopNode, for
example, would probably be more cumbersome and less expressive.
However, I'm not much experienced with activity modeling. Others on
this forum are (especially our fUML/ALF developers). Hopefully they
can provide more insight.
Cheers,
Christian
