 \begin{example}
 Consider:
 \begin{lstlisting}[language=modelica]
-annotation(…, Text(string = "1st Frequency is %f1."), 
-                Text(string = "2nd Frequency "+"is "+String(f2)+"."), $\ldots$);
+annotation($\ldots$, Text(string = "1st Frequency: %f1"), 
+                Text(string = "2nd Frequency: " + String(w2 / (2 * pi)), $\ldots$);
 \end{lstlisting}
-In this example only the string \lstinline!"1st Frequency is %f1."! can be translated, and no strings from the second line.
+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.
 \end{example}
 
 The files to support translation must be provided along with the library.
