### Question:
DMNIncludedNodeFactory { DRGElement drgElementWithNamespace(final DRGElement drgElement, final IncludedModel includeModel) { final String modelName = includeModel.getModelName(); drgElement.setName(createName(drgElement, modelName)); drgElement.setAllowOnlyVisualChange(true); if (drgElement instanceof HasVariable) { final HasVariable hasVariable = (HasVariable) drgElement; final IsInformationItem variable = hasVariable.getVariable(); final QName qName = variable.getTypeRef(); if (qName != null && !isBuiltInType(qName.getLocalPart())) { final QName typeRef = createTypeRef(modelName, qName); setVariable(hasVariable, variable, typeRef); } } return drgElement; }  DMNIncludedNode makeDMNIncludeNode(final String path,
                                              final IncludedModel includeModel,
                                              final DRGElement drgElement);  }### Answer:
