帮助自引用XSD生成循环引用

我正试图从XSD文件构建一个C#类。简言之，我在尝试执行XSD.exe工具时遇到循环引用错误：

来自的组“setFilterCondition” targetNamespace=http://developer.cognos.com /schemas/report/7.0/“已 无效定义：循环组引用

我提取了组的定义，并为其提供了以下XSD：

<xs:group name="setFilterCondition">
        <xs:annotation>
            <xs:documentation>Represents a simple or compound set filter condition</xs:documentation>

表示简单或复合的集合筛选条件
针对成员标题定义条件。
针对字符串成员属性定义条件。必须为除isNull和isNotNull之外的所有运算符提供value属性。
定义一个数值条件。条件可以是元组或成员属性。必须为除isNull和isNotNull之外的所有运算符提供value属性。
