This exists as a placeholder class so users may choose to parse Unknown Functions and have them appear in queries even if they cannot be evaluated. This is useful when you wish to parse a query locally to check syntactic validity before passing it to an external query processor which may understand how to evaluate the function. Using this placeholder also allows queries containing Unknown Functions to still be formatted properly.
