The SysMLv1 Block and ValueType structures shown in the Block Definition Diagram (BDD) are then used in Activities that model functions, as shown in the next slide for function sigsUp, which extracts styled UpValues signatures collated as a Column.

A value property corresponding to a Wolfram Language option is indicated by the «M:Opt» custom stereotype keyword.

Notes
[CONVENTION, NAMING, PATTERN, POLICY]{RECOMMENDED} Webel: Mathematica: CONVENTION: The Stereotype keyword «functional» indicates a "pseudo functional" representation of functional in SysML. There are limits to representation of functional programming in SysML, but it can be informative and is worth doing.
[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]{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.
[CONVENTION, NAMING, POLICY]{SUGGESTED} Webel: Mathematica: CONVENTION: A 'z$' prefix may be used to indicate a Private` function or expression within a package or a "private" method of an MTools class or Webel Abstract Data Type (ADT) stateless pseudo class.
