The whole interval description, all rows and columns, are collected in a panel named:
Name='TariffDynamicDescriptionPanel'. The rows and columns are then added as controls. See example below:
<TFT:Panel Name='TariffDynamicDescriptionPanel' >
<Controls>
<TFT:Label Name='Heading' FormattedText='Tariff@:' Location='0,0'/>
<TFT:Label Name='{TariffDynamicDescriptionLabel_1_1}'
Location='0,30' />
<TFT:Label Name='{TariffDynamicDescriptionLabel_1_2}'
Location='0,60' />
</Controls>
</TFT:Panel>
