This proposed registration is being distributed to this list (ietf-types@iana.org) for preliminary review, in accordance with the instructions given by IANA. It is cc'ed, as suggested by IANA, to Chris Newman. It is also cc'ed to 3GPP delegates to TSG CT WG1 (http://www.3gpp.org/tb/home.htm, http://www.3gpp.org/tb/CT/CT1/CT1.htm) who have a technical interest in the matter. Best regards John M Meredith 3GPP Specifications Manager, ETSI ======================================================================== ========================================
Name : John M Meredith (3GPP Specifications Manager) Email : john.meredith&etsi.org
MIME media type name: Application
MIME subtype name: 3gpp-ims+xml
Required parameters: None
Optional parameters: "charset" the parameter has identical semantics to the charset parameter of the "application/xml" media type as specified in RFC 3023 [132]. "sv" or "schemaversion" the parameter's value is used to indicate: - the versions of the 3GPP IM CN Subsystem XML schema that can be used to validate the 3GPP IM CN subsystem XML body (if the MIME type and parameter are present in the Content-Type header) or - the accepted versions of the 3GPP IM CN Subsystem XML body (if the MIME type and parameter are present in the Accept header).
If the "sv" or "schemaversion" parameter is absent, it shall be assumed that version 1 of the XML Schema for the IM CN subsystem XML body is supported.
This registration entry includes ABNF that modifies the m-parameter definition in RFC 3261 [26]. m-parameter allows for attribute/value pairs that are applicable to the media range. In particular, the ABNF below is given for a media range application/3gpp-ims+xml specific m-parameter.
m-parameter /= ("sv" / "schemaversion") EQUAL LDQUOT [ sv-value- list ] RDQUOT sv-value-list = sv-value-range *( "," sv-value ) sv-value-range = sv-value [ "-" sv-value ] sv-value = number / token number = 1*DIGIT [ "." 1*DIGIT ]
Encoding considerations: Same as encoding considerations of application/xml as specified in RFC 3023 [132]
Security considerations: 3GPP has defined mechanisms for ensuring the privacy and integrity protection of the bodies of SIP messages used in the 3GPP IM CN Subsystem.
Interoperability considerations: This content type provides a format for exchanging information in SIP Requests and Responses and used within the 3GPP IM CN Subsystem.
Published specification: ETSI TS 124 229 version 8.4.1, being a formal transposition of 3GPP TS 24.229 version 8.4.1: "Internet Protocol (IP) multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3"
