我正在尝试扩展 XSD 文件中的现有复杂类型。
我创建了一个新的 xsd 文件并将其包含在所有主 XSD 文件的末尾。
我遇到的问题是,它似乎添加了我的扩展,但它删除了 asset_abstract 中定义的元素以外的现有元素
我想做的事情可能吗?

我可以导入代码来扩展该方案。

好吧,我已经创建了一个简单的例子,但我现在仍然无法使用 Visual Studio 让它工作,因为我想确保它不是工具:),我仍然无法像你的那样工作:(我一定是缺少了什么。
基本上我添加了 2 个文件 Master.xsd 和 local.xsd Master 包装了我不能/不想直接修改的远程项目,而 local.xsd 是我们所有站点特定内容的所在(重新定义,因为它被称为)。

我最终在那里进行了所有的重新定义。
如果您想将复杂类型的名称保留为“Feature_Cadastre_Lot”并用其他内容扩展它,那么您正在考虑重新定义。最终效果是所有对“Feature_Cadastre_Lot”的引用(无论是现有的还是新的)都将包含新添加的内容。
如果您希望在某些而不是全部现有内容中使用此内容,则没有解决方案(重新定义是全部或全部)。
重新定义具有以下布局:
<xs:redefine schemaLocation="must resolve to your XSD">
<xs:complexType name="Feature_Cadastre_Lot">
<xs:complexContent>
<xs:extension base="Feature_Cadastre_Lot">
<xs:sequence>
<xs:element name="LMS_ID_1" type="String_32" minOccurs="1" maxOccurs="1" nillable="false">
<xs:annotation>
<xs:documentation>The Land Management System ID as defined by the LMS Team</xs:documentation>
</xs:annotation>
</xs:element>
<xs:element name="LMS_ID_2" type="String_32" minOccurs="1" maxOccurs="1" nillable="false">

结果将如下所示:

您可以看到突出显示的序列显示添加的内容。
在Visual Studio 2010中,内容也显示ok:

注意底部的第二个序列。
