 \begin{example}
 Consider:
 \begin{lstlisting}[language=modelica]
-annotation($\ldots$, Text(string = "1st Frequency: %f1"), 
+annotation($\ldots$, Text(string = "1st Frequency: %f1"),
                 Text(string = "2nd Frequency: " + String(w2 / (2 * pi)), $\ldots$);
 \end{lstlisting}
 In this example only \lstinline!"1st Frequency is %f1."! can be translated; the second \lstinline!Text.string! doesn't consist entirely of concatenated string literals, and is hence completely excluded from translation.
