This appendix gives a summary of some of the advanced notations that can be used with SysML sequence diagrams that allow the following to be shown: Parallel behaviour; References to other sequence diagrams; Alternative steps; Loops. The notation to allow these constructs are known as combined fragments. For full details, see Reference 1. Examples of the notation for each of these combined fragments showing how they are used are given in the following sections.
