  org.kie.internal.builder.help.DroolsJaxbHelperProvider.addXsdModel(Resource, KnowledgeBuilder, Options, String)
  This is now deprecated, as we now support XSD as a standard ResourceType. Although you'll still need the newJAXBContext method to create a JAXBContext from the KnowledgeBase.
  org.kie.internal.persistence.jpa.JPAKnowledgeService.loadStatefulKnowledgeSession(int, KieBase, KieSessionConfiguration, Environment)
