When the mediation primitive gets the request, it queries for all ports matching the port type identified in the properties.

在中介元素得到请求时，它将查询与属性中定义的端口类型匹配的所有端口。

In the mediation flow shown in Figure 15, any request processing must occur before Router custom mediation primitive, and any response processing must occur before the InputResponse node.

在图15所示的中介流中，任何请求处理必须发生在Router自定义中介元素之前，并且任何响应处理必须发生在InputResponse节点之前。

This value is important, as it will enable us to build an http request, allowing the XSLTransform primitive in the mediation flow to load it dynamically.

这个值很重要，因为有了它就可以构建 http 请求，使中介流中的 XSLTransform 原语可以动态地装载它。
