我正在尝试对 wsdl 文件使用 SvcUtil 来生成代理类，但是我遇到了一个元素丢失错误，我认为该错误与架构组元素有关。有谁知道 svcutil 是否可以处理的事实？如果是这样，它将处理具有指向另一个模式文件中的组定义的 ref 属性的 xs:group 元素吗？
SvcUtil.exe 命令（也包括 xsd 文件的路径）：
d:\codegen\svcutil.exe d:\codegen\RPE\ProtocolStateManager.wsdl d:\codegen\RPE\schema\RPE.xsd d:\codegen\RPE\schema\PORT_MT100001UV.xsd d:\codegen\RPE\schema\coreschemas\infrastructureRoot.xsd d:\codegen\RPE\schema\coreschemas\dataTypes.xsd d:\codegen\RPE\schema\coreschemas\voc.xsd /l:cs
错误是：
