请注意，所有这些工作都是针对规范形式的信息进行的，在与实际的服务提供者进行交互时无论使用什么样的格式和传输都是这样。

Notice that all of this work is done on a canonical form of the information, and would be the same regardless of the format and transport used to interact with the real service provider.

形式和内容分离：XML使得以不同格式表现相同的源内容成为可能——比如以We b页、打印稿或者其他提交媒介表现。

Separation of form from content: XML makes it possible to present the same source content in different formats — for example, as Web pages, printed pages, or other delivery media.

注意你可以用两种格式之一指定功能性软件需求：声明形式和用例形式。
