ISO 20022-5:2013是对ISO 20022-1:2013的补充。反向工程指南解释了如何从现有行业信息集中提取相关信息，以便准备向ISO 20022注册机构提交同等、符合ISO 20022的业务交易和信息集。 ISO 20022存储库将包含所有符合ISO 20022的业务事务和消息集，如ISO 20022-1:2013所述。

ISO 20022-5:2013 was prepared to complement ISO 20022-1:2013. The reverse engineering guidelines explain how to extract relevant information from existing IndustryMessageSets in order to prepare the submission to the ISO 20022 Registration Authority of equivalent, ISO 20022 compliant BusinessTransactions and MessageSets. The ISO 20022 Repository will contain all ISO 20022 compliant BusinessTransactions and MessageSets, as outlined in ISO 20022-1:2013.
