While you can reuse schema elements and schema types, consider the programming language that the WSDL will map to.

当重用模式元素和模式类型时，请考虑WSDL要映射的编程语言。

For example, one schema could define a key element as base64 data for storing a cryptographic key while another schema would define key as an integer for storing a database identifier.

例如，一个模式可能定义一个key元素为用于密钥的base64数据，而另一个模式将key定义为一个用于储存数据库标识符的整数。
