Thanks, Paul.
I posted the same question in another uml forum, and the answer was that sequence diagrams are preliminary design - a transition from analysis to design. Nor analysis or design. Then you copy the sequence diagram, and start refining it in a design stage. In a way, your answer is the same I got from the other forum.
