Hi all,

For part 2 (sequence diagram), diagram may need to refer to another one.
I know that I can use "ref" frame to represent this scenario in version UML 2.x. However, I want to use the UML 1.x construct (in fact my tool dosesn't support UML 2.x). How should one diagram reference (or reuse)another existing diagram using UML 1.x representation?

For another question, have you submit the sequence diagram for the alternative flow?

Thanks.
For part 2, I found that the use case spec. did not mention about the tasks of travel agent. Does it mean that the role performed for travel agent is the SAME as the customer?

However, for "create profile" use case, the travel agent should create profile of customer rather than himself/herself. For "Pay for Itinerary" use cse, how did the travel agent pay for itinerary using customer's(??) credit card?

Can travel agent be omitted in the class diagram ?

Rgds,
Alexis
