中文摘要：

在XACML（extensible access control markup language）和其管理性策略草案的基础上，针对目前XACML访问控制框架的特点，提出将XACML策略管理权限判定归结为利用委托策略对一个委托判定请求的判定，使用XML（extensible markup language）模式定义了此委托判定请求语法，描述了将策略管理请求规约为一个委托判定请求的过程，以及根据委托策略进行委托判定请求的判定过程，通过这种方法可以利用委托策略，对策略管理请求是否有效进行判断，从而实现基于扩展XACML的策略管理。

英文摘要：

Based on XACML core specification and XACML administrative policy draft, a decision of XACML policy management permission was reduced to a decision of delegation decision request. The delegation decision request schema was defined. It was described that the process of reducing a policy administration request to a delegation decision request and the decision process of delegation decision request. This method can be used to check if a policy administration request is valid and thereby to implement access control policy management based on extended-XACML.
