+The prefixes \lstinline!discrete!, \lstinline!parameter!, \lstinline!constant! of a component declaration are called \firstuse[variability!prefix]{variability prefixes} and are the basis for defining in which situation the variable values of a component are initialized (see \cref{events-and-synchronization} and \cref{initialization-initial-equation-and-initial-algorithm}) and when they are changed during transient analysis (i.e., solution of initial value problem of the hybrid DAE).
+Further details on how the prefixes relate to component variability, as well as rules applying to components the different variabilities, are given in \cref{component-variability}.

 \subsection{Acyclic Bindings of Constants and Parameters}\label{acyclic-bindings-of-constants-and-parameters}
 
 For a constant or parameter \lstinline!v! with declaration equation, the expression of the declaration equation in the flattended model must not depend on \lstinline!v! itself, neither directly nor indirectly via other variables' declaration equations.
