The INFOSPEC.INFO field contains a byte array that is specified by the data originator. Sometimes information must be included in a file for which none of the other records is suitable. When such information is human-readable, it should go into COMMENT records; when it is binary data or character flags, then it should go into an INFOSPEC record. The INFOSPEC.INFO field can contain anything; however, we strongly suggest that the first four bytes contain a long integer number that will uniquely identify what is contained after.
