IEC 62351-11:2016规定了保护IEC范围内使用的XML文档以及其他域中的文档的模式、过程和算法。如果需要安全交换，本部分旨在供标准参考，除非各方之间达成协议，以便使用其他公认的安全交换机制。IEC 62351的这一部分利用了著名的W3C XML文档安全标准，并提供了这些标准的分析和附加扩展。

IEC 62351-11:2016 specifies schema, procedures, and algorithms for securing XML documents that are used within the scope of the IEC as well as documents in other domains. This part is intended to be referenced by standards if secure exchanges are required, unless there is an agreement between parties in order to use other recognized secure exchange mechanisms. This part of IEC 62351 utilizes well-known W3C standards for XML document security and provides profiling of these standards and additional extensions.
