Internet Engineering Task Force (IETF) T. Hansen Request for Comments: 6839 AT&T Laboratories Updates: 3023 A. Melnikov Category: Informational Isode Ltd ISSN: 2070-1721 January 2013 Additional Media Type Structured Syntax Suffixes Abstract A content media type name sometimes includes partitioned meta- information distinguished by a structured syntax to permit noting an attribute of the media as a suffix to the name. This document defines several structured syntax suffixes for use with media type registrations. In particular, it defines and registers the "+json", "+ber", "+der", "+fastinfoset", "+wbxml" and "+zip" structured syntax suffixes, and provides a media type structured syntax suffix registration form for the "+xml" structured syntax suffix.

Introduction [RFC3023] created the +xml suffix convention that can be used when defining names for media types whose representation uses XML underneath. That is, they could have been successfully parsed as if the media type had been application/xml in addition to their being parsed as their media type that is using the +xml suffix. [RFC6838] defines the media type "Structured Syntax Suffix Registry" to be used for such structured syntax suffixes. A variety of structured syntax suffixes have already been used in some media type registrations, in particular "+json", "+der", "+fastinfoset", and "+wbxml". This document defines and registers these structured syntax suffixes in the Structured Syntax Suffix Registry, along with "+ber" and "+zip". In addition, this document updates [RFC3023] to formally register the "+xml" structured syntax suffix according to the procedure defined in [RFC6838]. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 2.
