The PMML model is quite extensive, and there isn't enough support in the ML
library for utilizing most of the things [like FieldUsageType, DataTypes etc.].
I had actually written the import functions for both SVM and MLR but decided to
drop them.
I mostly followed Spark's implementation for this, and it isn't supported
there either.
