Details of the use of this proforma is provided in this Recommendation | Part of ISO/IEC 10026. Implementors of implementations claiming conformance to ITU-T Rec. X.862 | ISO/IEC 10026-3 shall complete the proforma as part of the conformance requirements. The level of detail required in the proforma exceeds that of the protocol specification by requiring details to uniquely identify the implementation and the supplier. NOTE — PICS are related to base standards and only base standards. PICS Proforma structure might be expanded and refined for other documents (e.g. ISPs) using the base standards (e.g. ISPICS Proforma).
