SysPhS-1.1: GOTCHA: The term "initial values" is sometimes just used to refer to the start values for a simulation run in Modelica or Simulink. It does NOT always mean the additional context-specific values mechanism of SysML beyond Property::defaultValue
SysML: Using redefined Property and Property::defaultValue to create deep hierarchical value configurations of "initial values" configurations for SysPhS simulation is notoriously fiddly and requires experience and patience. Better tool support is needed!
