Requirements clarification

[Swamy Kumar]

The Pricing use case is only used by Prepare Itinerary and Change Itinerary use case. Can this be taken as an internal service not being exposed to the end customer ? The Pricing use case states that "All interaction with the customer and the system must be secured with SSL." - now why is there a need to expose the pricing use case to the end user ?

[giuseppe fanuzzi]

it can be a use case that is "included" in others use cases

[Swamy Kumar]

Included use case - fine. But the Q is should the end user access it ?

[giuseppe fanuzzi]

if the use case A includes the use case B, every time the user accesses to use case A, then automatically it accesses also to use case B.
The use case "A" can not lives without use case "B".
