XSD基本类型限制有什么问题

Question

我有一个 XSD，它引用了另一个具有受限类型的模式。当我使用 Liquid Studio 或任何其他类似应用程序打开它时，出现以下错误

根据 Elt:Elt -- NameAndTypeOK，'Derived element'http://www.saudiedi.com/schema/trfMafSts:record' 不是对基本元素'http://www.saudiedi.com/schema/sau:record' 的有效限制。

主架构文件（TRMFMAFSTS.xsd）

错误信息所指的规则在这里：https://www.w3.org/TR/xmlschema-1/#rcase-NameAndTypeOK

Schema 组件约束：粒子限制 OK (Elt:Elt -- NameAndTypeOK)

要使一个元素声明粒子成为另一个元素声明粒子的有效限制，以下所有条件都必须为真：

1 声明的 {name} 和 {target namespace} 相同。

2 ...

但是 TRFMAFSTS.xsd 中的本地元素声明“记录”与 saudiedi.xsd 中的本地元素声明位于不同的命名空间中。这是因为两种模式都有 elementFormDefault="qualified"，所以在每个模式中声明的本地元素都在该模式的目标命名空间中。

解决此问题的一种方法是使 TRFMAFSTS.xsd 中的“记录”元素成为全局元素，并在您的复杂类型限制中引用它。
