SYSML11 — 11.Activities, Figure11.10

Figure11.10 suggest use anonymous, typed Pins for clear indication of flowing information type and to support

indication of the Action ':Driving' without an output Pin corresponding to an underlying output Parameter of Behavior 'Driving' satisfying the 'isStream=true' condition. Indeed Table 11.1 - Graphical nodes included in activity diagrams shows only Actions with Pins and the

indicator for UML4SysML::Parameter.isStream The following image shows Figure 11.10 adapted to use Pins throughout (except for ControlValue input to the controller Action 'Monitor Traction'): http://school.nomagicasia.com/node/108 http://school.nomagicasia.com/files/images/Figure%2011.10%20-%20Continuous%20system%20example%201_%20Operate%20Car%20(adapted%20to%20use%20Pins,%20no%20annotations)_0.png NB: this issue submissions is marked as 'significant' because the I consider it extremely important that the SysML effort advertises the clear advantages of Pins whereever possible to the benefit of tool vendors and end users.
