Reference to a generator. Generator references can be used to create multi-resource federated generation models. Federated generation models can be used to keep reusable logic in shared models referenced by multiple other models. Model federation can also be used to keep the models of manageable size, simplify testing, and to facilitate team modeling by assigning different models to different team members.
Generator references would typically be used to reference generators defined in models in the same project or in generator models reacheable at both the modeling time and generation time.
See also GeneratorLink for another approach to referencing generators.
