错误是未声明 Item 元素?在标签中我有这个错误

error is The Item element is not declared? In label I have this error

推荐答案

为了能够引用一个元素，你必须将它设为全局.换句话说，您必须将Item 的声明直接移到xsd:schema 元素 下.在您的情况下，与 TWM_SAD

To be able to reference an element, you have to make it global. In other words, you have to move the declaration of Item directly under the xsd:schema element. In your case, at the same level as TWM_SAD

这是您更正且在语法上有效的 XSD:

This is your corrected and syntactically valid XSD:
