This International Standard specifies an XML protocol for the services defined in ISO/IEC 18051. It provides an alternative protocol to the ASN.1 based protocol specified in ISO/IEC 18052. In addition to the CSTA-specific protocol details, this International Standard describes the concepts underlying the request/response model, application association, notation and service, and describes the template used in this International Standard. It also specifies the PICS for this International Standard and provides examples of CSTA XML encodings.
