   JPMML-Model development branches 1.3.X and 1.4.X are generating PMML schema version 4.3 markup by default; the 1.5.X development branch will be started when the PMML schema version 4.4 is released. Perhaps this information will be useful for mapping PMML schema versions with Apache Spark development branches (2.X vs 3.X?).
   
   Your "native PMML integration" probably doesn't cover decision tree models yet. Anyway, there have been a couple of breaking JPMML-Model API changes in the latest 1.4.X versions (such as making the `org.dmg.pmml.tree.Node` class polymorphic), which are all aimed at reducing the memory consumption of the PMML class model object. There's a JPMML-Model version 1.4.9 coming up in a couple weeks time, which keeps moving the needle in this area.
