      a dictionary mapping the various node types to objects optionally containing preVisitor and transformer. The preVisitor allows you to provide TransformContext for the current object, altering how it will be transformed. The transformer allows you to manipulate the copy of the current object, and expects you to return the value that should take the current objects place.

    Returns Safe extends "unsafe" ? OutType : unknown

    the result of transforming the requested descendant operations (based on the preVisitor) using a transformer that works its way back up from the descendant to the startObject.
