The issue should be treated more general. The current implementation seems to follow a kind of 'stack-based' assignments of method calls and returns. I have not found any way how to specify what instance activation a given method call should be linked to. GraphViz uses a notion of ports. What about to extend the syntax in similar way, i.e. to enable a use of activity labels extending instance labels? For example: { A -> C:0; B -> C:1; A <-- C:0; B <-- C:1; } For example, this would enable to diagram a number of threads under one instance (like HTTP pipelining, etc in my case :-)).
