 The unexpanded binding equations for parameters and constants in the translated model must be acyclic after flattening; except that cycles are allowed if the cycles disappear when evaluating parameters having annotation \lstinline!Evaluate = true! that are not part of the cycle.
 Thus it is not possible to introduce equations for parameters by cyclic dependencies.
 
+\begin{nonnormative}
+There is no exception for parameters with \lstinline!fixed = false!, despite the fact that such parameters are generally allowed to be initialized from systems of dependent equations.
