 For FMI 3.0 FMUs, the connector name has to match either the name of the corresponding variable element, or one of its <Alias> elements.
 
 Names of variable elements of an FMU might follow the “Variable Naming Conventions” specification as defined by the FMI standard.

 Note that there is no requirement that connectors have to be present for all variables/ports of an underlying component implementation.
 At least those connectors *MUST* be present which are referenced in connections inside the SSD.

 This means that variables eligible for parameterization are those with:
 
 * either causality = "input" or a start value for FMI 1.0
-* variability != "constant" and initial = "exact" or "approx" for FMI 2.0
+* variability != "constant" and initial = "exact" or "approx" for FMI 2.0/3.0
 
 All kinds of system connectors can be parameterized.
 In case the system level connectors are connected to FMU components, the parameterization *MUST* be compatible with the variable in the connected FMU.
