UML 2.0 Elements for Sequence Diagrams

Following are elements for sequence diagrams as defined by UML 2.0:

• Frames: The sequence diagram is surrounded by a rectangular interaction frame. The interaction name shows in a compartment in the upper left-hand corner of the frame. In a sequence diagram, "sd" precedes the interaction name.
• Interaction Occurrences: Use the interaction occurrence to reuse interaction definitions.

NB: By default, Together uses the UML 1.4 specification for modeling diagrams. To enable UML 2.0 support, see Enabling UML 2.0 Features.
