Webel: SysML4Mathematica: Activity Diagrams used purely for analysis and as development aids are not required to show every ControlFlow, may omit InitialNode and ActivityFinalNode, and are not required to fully validate in SysML tools or execute.

Notes
[CONVENTION, MODELLING, NAMING]{RECOMMENDED} Webel: SysML4Mathematica: When modelling the main logic flow of Mathematica code with Activity Diagrams it isn't necessary to model every Mathematica construct. Placeholder Actions, OpaqueActions , and OpaqueBehaviors (as CallBehaviorActions) may be used.
[MODELLING, NAMING, TIP]{RECOMMENDED} Webel: SysML4Mathematica: Does every bit of the Mathematica code need to be modelled in SysML? No. Typically just the main function parameters and their interdependencies, data structures, and main code logic. Except for special or educational purposes.
[CONVENTION, MODELLING, NAMING]{INFORMATIVE} Webel: SysML4Mathematica: Activity Diagrams used purely for analysis and as development aids are not required to show every ControlFlow, may omit InitialNode and ActivityFinalNode, and are not required to fully validate in SysML tools or execute.
