Harden the `MiningSchema` element of ensemble models #171

Closed vruusmann closed 2 years ago

vruusmann commented 2 years ago

Example: https://github.com/jpmml/jpmml-evaluator/issues/237

Specifically, should add checks that:

  1. Missing values can't enter the model body.
  2. The Output element can't perform transformations on a missing prediction.
  3. One model segment can't pass a missing value to another segment.

Currently, specifying Segmenttation@missingPredictionTreatment="returnMissing" doesn't seem to suffice.
