(Registered 2019-08-14) Media type name: application Media subtype name: vnd.3gpp.mcvideo-info+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 section 9.1 of IETF RFC 7303. Encoding considerations: binary Security considerations: This XML-based media type inherits the general security considerations for application/xml media type as specified in section 9.1 of IETF RFC 7303. In addition, this media type provides a format for exchanging information in SIP, so the security considerations from IETF RFC 3261 apply. The information transported in this media type does not include active or executable content. Mechanisms for privacy and integrity protection of protocol parameters exist. Those mechanisms as well as authentication and further security mechanisms are described in 3GPP TS 24.229. This media type does not include provisions for directives that  institute actions on a recipient's files or other resources. This media type does not include provisions for directives that  institute actions that, while not directly harmful to the recipient,  may result in disclosure of information that either facilitates a  subsequent attack or else violates a recipient's privacy in any way. This media type does not employ compression. Interoperability considerations: Same as general interoperability considerations for application/xml  media type as specified in section 9.1 of IETF RFC 7303. Any unknown  XML elements and any unknown XML attributes are to be ignored by  recipient of the MIME body. Published specification: 3GPP TS 24.281 "Mission Critical Video (MCVideo) signalling control" version 14.7.0, available via http://www.3gpp.org/specifications/numbering.htm. Applications which use this media: Applications supporting the service continuity as described in the  published specification. Fragment identifier considerations: The handling in section 5 of IETF RFC 7303 applies. Restrictions on usage: none Provisional registration? (standards tree only): n/a Additional information: 1.
