Procedures similar to those described in RFC 3023, sections 8.9-8.11 should be used to determine the charset of a document. This media type is intended to be transported over HTTP/HTTPS or stored in files or databases. For transports not capable of handling binary content, encoding considerations from RFC 3023, section 3.2 will apply. It is RECOMMENDED to use UTF-8 for entities of this media type. Security considerations : The content of this media type is non-active and non-executable. The purpose of this media type is to transfer small amounts of data and implement message-based control protocols for video telephony networks. The information contained in the media type will in most cases be subject to security, integrity and privacy concerns. The media type does not provide any privacy or integrity services in itself. Applications using this media type will need to rely on mechanisms provided by transport protocols or data storage to satisfy their security requirements. General XML security considerations described in RFC 3023, section 10 also apply to this media type. The full spectrum of security issues associated with this media type has not been completely assessed. Interoperability considerations : This media type is intended for internal use by AvistarVOS(tm) software, as well as applications specifically designed to interoperate with it.
