限制中的XSD ref元素替换

Question

我遇到类型为MyC_COMPLEX_OBJECT_ATTRIBUTES_A ...无效限制的验证错误。我要执行的操作如下：我想从通用容器结构（C_COMPLEX_OBJECT）继承，并为每个容器设置一个具有特定结构（MyC_COMPLEX_OBJECT_A）和一组特定属性（ MyC_COMPLEX_OBJECT_ATTRIBUTES_A）...

有人希望有办法解决这个问题吗？ ...还是可以/应该更改通用结构吗？如果可以，怎么办？

注意：

A）我做block="extension"的原因是我要确保C_COMPLEX_OBJECT_ATTRIBUTES的子类型没有C_ATTRIBUTE以外的其他类型

B）我之所以没有创建C_ATTRIBUTE子元素（例如<xs:element name="value" type="MyC_ATTRIBUTE_A" substitutionGroup="C_ATTRIBUTE"/>，所以我要通过MyC_COMPLEX_OBJECT_ATTRIBUTES_A粘贴在ref="attributeA"中）的原因是，这些属性可以具有与一组派生的C_COMPLEX_OBJECTS同名...意味着可以有ObjectA.value和ObjectB.value（后者的类型不同...->我以唯一身份运行粒子归因问题）
