The specification then describes how explicit service contexts are mapped into the remote interface of a service, whereas implicit contexts are typically not.
规范因此描述了显式的服务上下文如何映射到服务的远程接口中，而隐式的上下文通常却不能这样做。
Support for multiple interfaces per object: in CORBA, the interface identifier is implicit because only one object interface is supported, whereas DCOM supports multiple interfaces per object.
支持一对象多接口：在CORBA中，接口标识符是固有的，因为它只支持一种对象接口。然而DCOM能支持一对象多接口。
You can probably guess by now what the interface will look like in the implicit header case.
现在宁可能会猜测隐式消息头实例中接口的形式。
