I have reviewed this document as part of the Operational directorate's  ongoing effort to review all IETF documents being processed by the IESG.  These comments were written with the intent of improving the operational aspects of the  IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.  Document editors and WG chairs should treat these comments just like any other last call comments.   This Informational document describes the text/markdown media type for use with markdown, a family of plain text formatting syntaxes that allows for the option to be converted to formal markup languages like HTML. This seems to be useful, but as far as I can tell does not have any direct operational impact and does not require for any manageability considerations. The 5706 review does not apply. From the OPPS perspective this document is ready.   Regards,   Dan
