[Element] prefer-renderer [Data Type (for the value)] boolean (true, false) [Default Value] false [Description] 
By default, FOP prefers the newer output implementations based on the IFDocumentHandler interface. If no such implementation can be found for a given MIME type, it looks for an implementation of the Renderer interface. If necessary, you can invert the lookup order to prefer the Renderer variant over the IFDocumentHandler variant by setting this value to true.
