The ShiftType, ShiftSize, ShiftScheme nodes take an optional attribute key that allows to configure different values for
6017+
different sensitivity templates. The sensitivity templates are defined in the pricing engine configuration. This is best
6018+
explained by an example: In Example 15 the product type BermudanSwaption has a sensitivity template \verb+IR_FD+
6019+
attached, see \ref{lst:sensi_template}. This can be used to specify different shifts for trades that were built against
6020+
this engine configuration, see \ref{lst:sensi_config_template}: For Bermudan swaptions a larger shift size of 10bp and a
6021+
central difference scheme is used to compute discount curve sensitivities in EUR. Since no separate shift type is
6022+
specified, the default shift type {\tt Absolute} is used. Note regarding the reports:
6023+
6024+
\begin{itemize}
6025+
\item the sensi scenario report contains scenario NPVs related to the possibly product specific configured shift sizes
6026+
\item the sensi report contains renormalized sensitivities, i.e. sensitivities are always expressed w.r.t. the default shift sizes
6027+
\item the sensi config report only contains the default configuration
