---------------------------------------

Major infrastructure changes to properly support error validation are now implemented. Type definition and resolution is now correlated between DMN layer and FEEL layer. Additional work will be done through other tickets.

> When a model contains errors that prevent compilation, the engine should provide a better error message pointing to the specific error.
> At the moment, the attached model fails with a NPE and a message:
> {quote}Message [id=1, kieBase=defaultKieBase, level=ERROR, path=car_damage_responsibility2.dmn, line=-1, column=0 text=Unable to compile DMN model for the resource]{quote}
