Detailed Description
An unrecognized prototype model.
This kind of model is created for function prototypes that specify a model name for which there is no matching object. A model is created for the name by cloning behavior from a placeholder model, usually the default model. This object mostly behaves like its placeholder model but can identify itself as an unknown model and adopts the unrecognized model name.
