For me it would be logical to have a seperate model input which contains
information about the tool structure, for example a UML class diagram?
If not possible you have to find some way to encode it into your sequence
diagrams. Maybe you can store a reference in the class that calls the
constructor.

Doesn't this depend on the overlapping of the liftimes, when to create l2
and l3? Does it become clearer if you include constructor calls in your
sequence diagrams?

First of all, thanks for the help, about the question 1 we suspected that
we could need another model, i was simply trying to avoid the use of this
model, but it seems it the logical solution.
About question 2, sorry but i didnŽt understood what did you mean, could
you explain with other words? Trying to explain to problem a bit more, i
already have these 3 objects created, my doubts are about the method flow
between then, honestly i think itŽs the option A but iŽm not sure.
Thanks in advance
Hugo Marques
