PD CEN/TS 15121-1:2011 Postal Services - Hybrid Mail - Part 1: Secured electronic postal services (SePS) interface specification - Concepts, schemas and operations
This document specifies a standard XML interface that will enable software applications to call a secured electronic postal service (SePS), provided by a postal service, which is based on the concepts, schemas and operations described herein. The specification provides: a definition of standard operations which can be combined to support secured electronic postal services; a full description of all mandatory and optional request parameters required for use of these operations; a full description of all response elements and the detailed circumstances under which they are returned. The specification also describes the functionality and edit rules of the actual technical specification artifacts, which are represented by an XML Schema (XSD) and an associated Web Services Definition Language (WSDL) specification. The SePS schema specification in Annex A is discreet and version specific. Postal Services are free to select which discrete interface versions they support. However, except in the case of upgrades to V5 adopted to ensure cross-border compatibility, postal services who upgrade from older versions of the schema (e. g. from V4) to a newer one are required to support backward compatibility of previously supported versions of the SePS interface specification as it applies to both processing requests/responses and honoring previously issued PostMarkedReceipts. Individual posts are free to addressThis backward compatibility challenge as they see fit. The SePS Interface specification includes a digital signature platform supporting basic cryptographic service operations as well as a comprehensive framework for the delivery of evidentiary, witnessing, and non-repudiation services. The specification provides for continued support of legacy CMS/PKCS7 binary signatures.This approach allows subscribing applications to leverage the strengths of both protocols and can aid in the migration from one to the other. The schema will continue to support, in an interchangeable way, use of both CMS/PKCS7 and XMLDSIG artifacts. SePS implementations are free to support the "XML Signature Syntax and Processing" standard (i.e. XMLDSIG) for all elements presently carrying PKCS7 content. Selection of either format is supported across the two prevalent signature formats withinThis domain. XML Encryption is also supported.
