> A codegen facility is required to generate statically code strongly typed for the input/output of a DMN model, considering also the data types defined inside the DMN model as ItemDefinition. 
> Surface and interface common to:
> * BPMN integration: when invoking DMN from BPMN, the return of the evaluation is a Map and not the domain model
> * Kogito/OpenAPI/Swagger: when using the codegenerated version, annotation shall explain the swagger API the expected input/output type of the REST request for DMN
> ** for Quarkus based, use RegisterForReflection annotation
> ** use MP validation for allowedvalues 
> * DMN Editor: when importing a Java Class in the editor, it shall use the user-supplied Java Class 
> Documentation:
> * the programmatic use of the generated classes, directly, is DISCOURAGED
> * if anything, a programmatic use will eventually be stable by making use of the available interfaces in kie-dmn-core
