With either development style, the end goal is the same – you want a stable WSDL+schema definition of your service.

不论使用哪种开发风格，最终目标都是相同的——你想要你的服务有一个稳定的WSDL+模式定义。

Loosely typed means that the interface definition of the service (in WSDL) does not contain a schema that strongly defines any kind of message format that that the service USES.

松散类型意味着服务的接口定义(使用WSDL)不包含强定义服务所使用的任何消息格式的架构。

For instance, in a Web service definition, there is a good chance that the XML schema will map to a programming language.

例如，在一个Web服务定义中，XML架构很有可能会映射到一种编程语言。
