在EMIF框架下，应用程序代理与ZIS通过EMIF规定的报文进行数据交换，报文是标准的XML文档。应用程序代

理与ZIS接收到报文后，首先要验证该XML报文是否符合EMIF规范。本文根据EMIF规范构建了EMIF报文的XML

Schema文档，并给出了在．NET下实现报文有效性验证的算法。-Based on EMIF，application agent or ZIS exchanges its information with each other th~ush the message stipulated by

EMIF，which are the standard XML documents．After the application agent or ZIS receives the message，it first must confirm

whether this XML document COnfOrm S to the EMIF standard．The paper constructs XIVIL Schema docum ents ofEMIF message ac—

coming to EMIF standard，and presents the algorithm to realize validation of the message based On．NET framework．
