            指示是在客户端（client）还是在服务器端（server）保存UI组件的状态和
            session信息, server表示保存到服务器端,client表示保存到客户端,

            当使用扩展名映射（后缀映射）时，所使用的资源的默认后缀
            默认为.jsp，它自于javax.faces.application.ViewHandler
            类中的常量. 常量的名字是 DEFAULT_SUFFIX 值相当于 ".jsp"

            Set this flag to true if you want the JSF
            Reference Implementation to verify that all of the application
            objects you have configured (components, converters,
            renderers, and validators) can be successfully created.
            Default value is false.
            告诉JSF验证其可以创建应用对象(组件，呈现器，转换器等)， 
            那么设置标志为true， 默认值为false。

            Set this flag to true if you want the JavaServer Faces
            Reference Implementation to validate the XML in your
            faces-config.xml resources against the DTD. Default
            value is false. 
            告诉JSF根据DTD验证配置文件，
            那么设置标志为true， 默认值为false。

            Setting this to true will cause the FaceletViewHandler
            to print out debug information in an easy to use screen
            when an error occurs during the rendering process。
            很显然，为了方便开发，我们应该设置。
