This specification provides three main mechanisms: security token propagation, message integrity, and message confidentiality
一个典型的符合WS-Security标准的Soap消息
插入代码好像不能用了

很多Sercurity的东西都在SoapHeader中体现！
9－29行是标准中的Security Header,其包含了预定接收者所需的Security Infomation
10－12行是分配给该消息的Security Token,在本例中，客户端使用UsernameToken,并且没有在Soap消息中传送密码，所以我们可以假定通讯双方早先已经确定了认证的密码(It's a shared secret)
13-28行是对数字签名的完整描述，这个签名保证签名元素的完整性，该签名使用了XML Signature specification.在本例中，这个签名基于一个从User Password生成的Key当中
15行 specifies how to canonicalize (normalize) the data that is being signed
17－20行选择北签名的元素，17行指明了为<S:Body>的元素将被签名
22行specifies the signature value of the canonicalized form of the data that is being signed as defined in the XML Signature specification.
23－27行提供一个到那里去寻找分配给security token的签名的Uri的暗示(hint) ；
31－33行包含了对我们有用的Soap消息体
