Hi,
Thanks for opening the Bugzilla Ernesto. I will try to add some information to it, including some example model that shows how a legacy model looks like with these constants. I will also clarify this aspect, including that we probably should have a similar Browse... button next to the replication factor for ports and capsule parts in the related tooling Bugzillas.
Please keep in mind that we not necessarily need to support this mechanism for multiplicity for normal attributes. The UI in the legacy tooling does not support this Browse... button. But I guess as you have indicated in the Bugzilla, that we will get the support for it in the code-generator for "free" anyway. I am not sure though how much effort we shall spend on adding it to the tooling since the multiplicity for normal attributes probably will use the default tooling from base Papyrus, e.g. we will not have this speicific "Replication" field that is proposed in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=479350 and
https://bugs.eclipse.org/bugs/show_bug.cgi?id=479352.
