Hi, In the business domain model, the Itinerary has a 1...1* relationship with the Segment. How would you model such a relationship? 1..1 is a reference. 1..0* is a list. Not sure how 1...1* might be modeled. Any thoughts?

You never encounter an emply list. Say in Java, ArrayList can exist but its size can be zero, one or more than one. right? So, if you use a List it will cover all the cases.
