Encapsulates information about the result that should be produced when a OldDynamicAction cannot be performed. The ErrorInfo can hold one of: an expression which creates an Exception to be thrown an expression which produces a value which should be returned directly to the user and represents an error has occured (for example undefined in JavaScript) an expression which produces a value which should be returned directly to the user but does not actually represent an error. ErrorInfo's are produced by an ActionBinder in response to a failed binding.
