 * Argument `nContinuousStates` points to the `size_t` variable that will receive the number of <<state,states>>.
 
 +
+The initial value of `nContinuousStates` is the sum of the sizes of the variables referenced by the <<ContinuousStateDerivative>> elements.
 The number of <<state,continuous states>> might change if a variable representing a state has a <<Dimension>> element that references a <<structuralParameter,`structural parameter`>> (see <<ConfigurationMode>> and <<ReconfigurationMode>>).
 <<fmi3GetNumberOfContinuousStates>> must be called after such <<structuralParameter,`structural parameters`>> changed.
 As long as no <<structuralParameter,`structural parameters`>> changed, the number of states is given in the <<modelDescription.xml>>, alleviating the need to call this function.
