当与明确指定的元素冲突时，它们不再违背UPA，它们可以排除一组名称空间或一组名称，甚至可以设置默认通配符。
They no longer violate UPA when conflicting with explicitly specified elements, they can exclude a list of namespaces or a list of names, and they can even be defaulted.
排除列：您希望被排除的列名称可以为空。
Exclude columns: the name of the columns that you want to be excluded can be null.
这个默认行为克服了WebSphere Application Server ND中的限制，排除了用给定的应用程序名称在非集群(non - clustered)环境中执行多次安装。
This default overcomes the restriction in WebSphere application Server ND that precludes the installation of a given application name more than once in a non-clustered environment.
