the generated go file contains a field in a struct that is not in the definition

[sumia01]

Description

I'm trying to generate structs for go from the schema provided by Tableau (link below), but I'm getting bad results for this XSD version. For comparison, I'm using c# sourcecode generated with xsd (from mono).

The result structures are different than expected.

Steps to reproduce the issue:

1. get xsd file from https://help.tableau.com/samples/en-us/rest_api/ts-api_3_17.xsd or use https://gist.github.com/sumia01/f15ee5589f4a020b63bd0e016ebaf5b6#file-ts-api_3_17-xsd
2. generate output file(s)

xgen -i ts-api_3_17.xsd -o 3.17/schema.go -l Go

3. compare with reference generated with xsd from Mono (https://www.mono-project.com/docs/getting-started/install). I uploaded it here: https://gist.github.com/sumia01/f551985805e2e84c9a83cee1e9ef59f8

Describe the results you received:
In the generated result, there is a Status string in the SiteType struct.
https://gist.github.com/sumia01/f15ee5589f4a020b63bd0e016ebaf5b6#file-schema-go-L1511

But it shouldn't be there, see the c# reference:
https://gist.github.com/sumia01/f551985805e2e84c9a83cee1e9ef59f8#file-tableau_3_17-cs-L2960

And here is the type definition part from the original xsd, I can't find any reference for status here:
https://gist.github.com/sumia01/f15ee5589f4a020b63bd0e016ebaf5b6#file-ts-api_3_17-xsd-L1797

One more strange behaviour found here. If I comment the following part from xsd (https://gist.github.com/sumia01/f15ee5589f4a020b63bd0e016ebaf5b6#file-ts-api_3_17-xsd-L1418)

            <!-- <xs:element name="status" minOccurs="1" maxOccurs="1">
                <xs:simpleType>
                    <xs:restriction base="xs:string">
                        <xs:enumeration value="Failed" />
                        <xs:enumeration value="Success" />
                    </xs:restriction>
                </xs:simpleType>
            </xs:element> -->

then it's not generated into the SiteType struct. But I don't understand the connection here.

Describe the results you expected:

I'd like to get the same result as in the c# file
