1、wsdl做为一种xml协议,他主要是通过binding来进行扩展..并不需要去修改原wsdl的其他元素详细
2、wsdl的document元素主要用于 as a container for human readable documentation,用于描述
3、types :The types element encloses data type definitions that are relevant for the exchanged messages,用于说明消息交换的数据的类型...
. For maximum interoperability and platform neutrality, WSDL prefers the use of XSD as the canonical type system, and treats it as the intrinsic type system.
<definitions .... > <types> <xsd:schema .... />* </types> </definitions>
为了最大化的使用wsdl,所以wsdl通常使用xsd做为系统默认的规范和语法
