创建基本的 XACML 组件的过程：策略，包括规则和策略目标、策略实施点PEP、策略决策点PDP，掌握这些知识之后，就可以在当前和将来的应用程序中采用 XACML 处理访问控制。我们将以一个具体的 访问请求为例，创建所需的全部 XACML 组件。访问请求如下：主体mverma@secf.com 属于 owner 组（主体的属性），它尝试对资源 file:///D:/Documents/Administrator/Desktop/Project Plan.html执行 open 动作。这是实现XACML的基本功能的入门代码示例，便于新手入门

-XACML components to create the basic process: strategies, including rules and strategic objectives, policy enforcement point PEP, policy decision point PDP, to master this knowledge, you can in the current and future applications using XACML access control processing. We will visit a specific request, for example, XACML to create all the necessary components. Access request as follows: the main mverma@secf.com is owner group (subject property), it tries to resource file:///D:/Documents/Administrator/Desktop/Project Plan.html implementation of open action.
