This approach has limits in SysML (which is primarily strongly typed) compared with the powerful Pattern-matching approach of the Wolfram Language, but enables flexible encapsulation of a wide range of Mathematica functions and their parameters as Activities and SysML ConstraintBlocks with constraint parameters.

[CONVENTION, MODELLING, NAMING]{RECOMMENDED} Webel: SysML4Mathematica: An '@' prefix in the name of a Block indicates a Mathematica data structure (such as an Association or List) that is not represented by an MTools class in the Mathematica code
[CONVENTION, MODELLING, NAMING]{RECOMMENDED} Webel: SysML4Mathematica: An '@' prefix in the name of a ConstraintBlock, Activity, or OpaqueBehavior indicates that it is not represented by a dedicated function in a Mathematica code library (typically for minor maths or logic)
