OpaqueExpression

Webel: SysML4Mathematica: POLICY: Handle flow sign changes via a single negative (not duplicated and "adjusted" algebra). This strategy may come at a very slight performance cost (for benefit of more robustness).

MagicDraw/Cameo v19SP3: The display of units can't be disabled on the initialValues compartment for context-specific values, which can lead to inconsistencies when an OpaqueExpression that references value property names is used.

MagicDraw/Cameo v19SP3: UML/SysML: HOWTO Set an OpaqueExpression on a Slot that seems to be stuck on a numerical value.

MagicDraw/Cameo v19SP3: vs SysPhS-1.1: OpaqueExpression for Slot value exports to Modelica as 'null' if only uses a single variable. WORKAROUND/HACK prefix the variable with '1 *' [FIXED in v2021x]
