ISO/IEC 14165-312:2009（E）旨在作为实施指南，最大限度地提高一致性实施之间的互操作性。它需要可选功能，并禁止在参考规范中使用某些非可选功能。此外，它还简化了实现及其相关的文档、测试和支持需求。

ISO/IEC 14165-312:2009(E) is intended to serve as an implementation guide to maximize the likelihood of interoperability between conforming implementations. It requires features that are optional, and prohibits the use of some non-optional features in the referenced specifications. In addition it simplifies implementations and their associated documentation, testing, and support requirements.
