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.

RFC 6839 Additional Media Type Suffixes January 2013
1. 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].
