How to create a scorecard in PMML while using decimal values or negative values as input?

Question

following https://dmg.org/pmml/v4-1/Scorecard.html

and specifically https://www.smartdatacollective.com/25091/

I am building a scorecard model. When I use it with jpmml evaluator I get no result if the MiningSchema contains either negative or decimal input variables.

Below is a snapshot of the file:

          </CompoundPredicate>
        </Attribute>
 [...]

So my question is if this is an expected behavior? I did not find references in the documentation. Which alternative method can I use to implement scorecards in PMML?
