When two or more references are provided, a narrative line, indicated by the identifier NARR/, must be included. The narrative line explains the importance of the references. The acronym NOTAL (not to or needed by all) is used to indicate that some addressees do not hold the referenced material. The acronym PASEP (passed separately) is used to indicate that the reference  has  been  passed  separately  to  some  or  all addresses of the message. POINT  OF  CONTACT.—The   set   identifier POC/  indicates  the  message  or  information  point  of contact (POC) at the originating command. The rank and name of the POC is followed by the command name or code, and by the telephone number, all set off by slants. This field is mandatory on all GENADMIN messages. ACKNOWLEDGEMENT  INSTRUC- TIONS.—If  receipt  of  the  message  is  required  in writing   or   by   message,   special   message acknowledgement   instructions   may   be   entered following the set identifier AKNLDG/. REMARKS.—Now  look  back  at  figure  l-12. Following the RMK/ set identifier is the actual text of the message. Numbered paragraphs may be used, but are not required. Be  sure  to  mark  paragraphs  of classified messages with the appropriate classification symbol. DECLASSIFICATION. —Declassification instructions must be included on every classified message. This entry is not used on unclassified, EFTO, or FOUO messages. Insert the date or event (which must be less than 10 years from the origination date of the  message).  Certain  categories  of  information  are exempt from the 1 O-year rule and are indicated with the codes X1 through X8. While many forecast products transmitted via AUTODIN follow the USMTF GENADMIN format, certain coded products, such as synoptic ship surface weather  observations  and  ship  upper-air  observations follow a free format. Free Format Message Body The free format message uses the same style header and  classification  line,  but  the  remaining  message  body is much simpler (fig. 1-14). Notice that none of the information included in the body is set off in slants. Free  form  messages  may  also  use  a  numbered paragraph and lettered subparagraph convention if necessary for clarity. When numbered paragraphs are used in classified free-form messages, a classification marking for each paragraph follows the paragraph number,  as  shown  previously  in  figure  l-12.
