In a normal-form policy expression, all these nested policy assertions must themselves also be in normal form.
在一个标准形式策略表达式中，所有这些嵌套的策略断言必须是标准形式。
Besides simplifying element nesting, compact expression also provides a way to reference and reuse policy expressions.
除了简化元素嵌入，紧凑表达式也提供一种引用和重用策略表达式的方法。
For convenience, WS-Policy defines both a normal-form expression of a policy and a set of rules you can use to create more-compact policy expressions.
为了方便起见，WS - Policy定义了一个标准形式的策略表达式和一组可以创建更紧凑的策略表达式的规则。
Derived artifact - artifacts dynamically created as a result of publishing documents supported by derivation model, for example, WSDL PortType or Policy Expression.
派生工件-作为发布支持派生模型的文档的结果而自动创建的工件，比如WSDLPortType或策略表示。
Storage areas that satisfy the expression are associated to this storage policy.
满足表达式的存储区域被关联到这个存储策略。
A filter expression to select storage areas based on their name can be useful when adding additional storage areas to an existing policy.
当添加额外存储区域到已有策略时，根据存储区域名称选择存储区域的筛选器表达式会比较有用。
The normal-form expression of a policy can be lengthy, especially if it involves nested alternatives.
标准形式策略表达式是冗长的，特别是如果它包含嵌套替代项。
Storage policy filters are used to examine the properties of candidate storage areas, and to determine which storage areas satisfy the filter expression.
存储策略筛选器用于检查候选存储区域的属性，确定哪些存储区域满足筛选器表达式。
This section describes how to use a storage policy filter expression to perform specialized selection of a storage area.
本节描述如何使用存储策略筛选器表达式更具体地选择存储区域。
Following is a list of the StorageArea properties that you cannot use in a storage policy filter expression.
下面是存储区域筛选器表达式中不能使用的StorageArea属性。
WS-Policy defines a framework and a model for the expression of these properties as policies.
WS - Policy定义了用于将这些属性表述为策略的框架和模型。
If you do not specify an expression for Allowed members, all members of the dimension are considered to be accessible by a role that is assigned the policy.
如果没有为allowedMembers指定表达式，那么将认为该维度的所有成员都可以被分配了策略的角色访问。
In this paper, we make some researches on the XML query structure and analyze the optimization policy in logical optimization. How to optimize the path expression is discussed primarily in this paper.
