If you | have selected 2f, you must provide a defintion of the comparison. | Definitions by included reference must be to stable and readily | available specifications: | | If the number of alternative results is small, you may | enumerate the identifiers of the different results and describe | their meaning. | | If there is a limited useful numeric range of result (2b, 2c), | indicate the range. | | The identifiers of the alternative results could also be | described by referring to another IANA registry, for example | the paper sizes enumerated by the Printer MIB.
