GCAM v7.1 - Trouble with supply_demand curves.xml

[Arlo23RS]

Hi,

I am trying to output the supply and demand curves from my GCAM run from specified markets in "supply_demand_curves.xml".

Problem is I get an Unknown tag : supply-demand-curve-saver error and the csv never gets written out.

Thank you for your help.

What I have tried is :
Configuration>

SDCurves.csv

and in Scenario Components

../input/extra/supply_demand_curves.xml
