I am very new to Go and unable to find help on other sources. I am trying to create go code with standard vim25.wsdl file. It generated the go code successfully. Two structures are here..

type RetrieveServiceContentRequestType struct {
XMLName xml.Name xml:"urn:vim25 RetrieveServiceContentRequestType"

This *ManagedObjectReference `xml:"_this,omitempty"`

}

type ManagedObjectReference struct {
XMLName xml.Name xml:"urn:vim25 ManagedObjectReference"

Value string

Type string `xml:"type,attr,omitempty"`

}

Now I am unable to assign values to RetrieveServiceContentRequestType as follows with following error:
client := mysoap.NewVimPortType("https://myvc/sdk", true)

var serviceInstance = mysoap.ManagedObjectReference{
    Type:  "ServiceInstance",
    Value: "ServiceInstance",
}
fmt.Println(serviceInstance)
req := mysoap.RetrieveServiceContentRequestType{
    This: &serviceInstance,
}
_, err:= client.RetrieveServiceContent(&req)

Error xml: name "_this" in tag of mysoap.RetrieveServiceContentRequestType.This
conflicts with name "ManagedObjectReference" in *mysoap.ManagedObjectReference.X
MLName

Any help would be appreciated.
