该问题的核心部分是控制可以调用的应用程序或端点。

首先，数据绑定代码很容易和能够控制的端点紧紧捆绑在一起。
First, it's easy to tightly couple your data binding code to the endpoint that you control.
在控制一个端点时，仍然要像两个端点都不能控制那样编写和数据绑定交互的接口。
When you control one endpoint, you still write the interface into and out of your data binding as if you don't control either endpoint.

端点都不在控制之中：这种情况称为传递数据。
Neither endpoint is under your control: This is a case I call passthrough data.
如果只能控制一个端点，实际上问题比第一眼看起来更加微妙一些。
When you control one endpoint but not the other, the problems are actually a little more subtle than you might at first think.
取决于流程内的其他数据，您可能来到要使用的服务端点，也可能通过您在控制流程流的过程中进行的UDDI查询来接收服务端点。
Depending on other data in your process, you might come across the service endpoint to use, or you might receive a service endpoint via a UDDI query you do during your control flow of the process.
如果不能控制这个端点，就必须想办法适应它。
You're going to have to work with that if you have no control over the endpoint.
可以控制一个端点：这是最常见的情况，有一个端点可以控制，而另一端则是固定的。
One endpoint is under your control: This is the most common scenario, and results from having one endpoint accessible, but the other one fixed.
事实上，我回想起只有一次，我在数据绑定中完全控制了两个端点。
In fact, I can't recall a single time when I've had complete control over both endpoints in a data binding situation.
数据绑定很容易和控制的端点紧紧捆在一起，对于不能控制的端点也可能出现这种情况。
Just as you can tightly integrate your data binding into the endpoint that you control, you can do the same with the endpoint that you don't control.
选择性消费者路由器（SelectiveConsumer Router）用于入站端点，它可以控制服务处理哪些消息。
The Selective Consumer Router works on inbound endpoints to control which messages that service will process.
过滤路由器（Filtering Router）用于出站端点，可以控制哪些消息发送到下一个服务上。
The Filtering Router works on outbound endpoints to control which messages the service sends along to the next endpoint.
使用 WS-Polling，端点可以完全控制消息传递到其引擎以进行处理的频率。
Using WS-Polling, an endpoint has complete control over how often messages are delivered to its engine for processing.
该如何对端点进行版本控制？
这就允许同步环境尝试模拟异步消息传递——或者，换个说法，发送方重新得到向任何特定端点发送哪个消息的控制权。
This allows a synchronous environment to try to simulate an asynchronous one — or said another way, the sender regains control over which message to send to any particular endpoint.
更常见的情况是可以控制(或者至少能够影响)一个端点，但不能控制另一个端点。
A much more common case is the scenario where you control (or can at least influence) one endpoint, but not the other.
客户机在调用服务端点后立即获得执行控制权。
The client gets the control of execution immediately after calling the service endpoint.
奇怪的是，这种情况下的决策相对要简单一些，就像能够控制两个端点那样。
Oddly enough, the decisions in this case are relatively simple — just as they are when you have control of both endpoints.
要解决端点的版本控制问题，端点要做的第一步就是把文档解开，确定已经传输的内容，并用预期的内容与之协调。
To handle versioning of the endpoint, the first resolution step of the endpoint is to unpackage the document, determine what has been passed, and reconcile that with what is expected.
