SYSML11 — Section: 11.4

There is reference to timelines in 11.1.5. This is widely considered a critical capability for SysML, but there is not example in the spec. Add a usage example of an activity diagram with timing constraints and the corresponding timing diagram as referred to in 11.1.5.

Revise to show an example if timing constraints on activity diagrams. The portion of the issue concerning timing diagrams is not addressed by this resolution. It can be refiled as a separate issue.
A specialized notation for time and duration constraints (e.g., straight lines and arrows associated with the constraints) and more sophisticated examples (e.g., illustration of the time and duration Observation concepts of the Simple Time Model) in Activity diagrams, as supported by UML sequence diagrams, can be considered in separated issues.
