> Currently, StringSubstitutor is not replacing a variable that is unknown. It would \
> be nice to define the behavior  in this case and to allow raising an exception. A \
> workaround is to define a custom StringLookup that raises an exception when the \
> variable is  unknown but this prevent from using the default value feature from \
> StringSubstitutor
