Is there any way to create a leader trait so that the civ gets +25% production? I know how to make a trait that gives a bonus of a constant amount but not a percent.

The forge, a building, gives what a want using these tags:

YieldModifiers>
				
                 iYield>0
				iYield>25
				
                iYield>0
YieldModifiers>

Unfortunately, YieldModifiers doesn't seem to be a part of the Civ4TraitInfos schema. Anyone know if it is possible to do what I want?
