【问题描述】：

我对以下架构有疑问我想将 job 元素的 jobGroup 属性与 jobGroup 元素的 name 属性“匹配”，但我无法通过验证来验证此成本约束

这是我的架构和应该失败的示例

【解决方案1】：

您忘记在选择器中使用完全限定名称。您缺少命名空间。

试试这个：

<xs:element name="cluster" type="tns:clusterType">
    <xs:keyref name="jobGroupKeyRef" refer="tns:jobGroupKey">
        <xs:selector xpath=".//tns:job"></xs:selector>
        <xs:field xpath="@jobGroup"></xs:field>
    </xs:keyref>
    <xs:key name="jobGroupKey">
        <xs:selector xpath=".//tns:jobGroup"></xs:selector>
        <xs:field xpath="@name"></xs:field>
    </xs:key>
</xs:element>
