Summary:
Sequence diagrams are often used for early specification of requirements. The distinction between potential and mandatory behavior is not adequately described in UML 2.0 Interactions. To improve this we suggest an additional operator "xalt" that describes alternative operands that are mandatory meaning that any refinement should keep at least some of the behavior of each operand. See paper at <<UML2003>>: Haugen, Stølen: STAIRS - Steps to Analyze Interactions with Refinement Semantics
