Child element omitted if attribute with enumeration is passed

Description

I've tried to boil it down to the simplest example. I have an XSD as follows:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="template">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="requests"/>
        <xs:element minOccurs="0" ref="responses"/>
      </xs:sequence>
      <xs:attribute name="type" use="required">
        <xs:simpleType>
          <xs:restriction base="xs:string">
            <xs:enumeration value="avp"/>
            <xs:enumeration value="condition"/>
            <xs:enumeration value="routing"/>
          </xs:restriction>
        </xs:simpleType>
      </xs:attribute>
    </xs:complexType>
  </xs:element>
  <xs:element name="requests" />
  <xs:element name="responses" />
</xs:schema>

After generating, the following is generated:

// Code generated by xgen. DO NOT EDIT.

package schema

import (
	"encoding/xml"
)

// Template ...
type Template struct {
	XMLName  xml.Name    `xml:"template"`
	TypeAttr interface{} `xml:"type,attr"`
	Requests *Requests   `xml:"requests"`
	Template string      `xml:"template"`
}

// Requests ...
type Requests *Requests

// Responses ...
type Responses *Responses

This is missing the Responses key in the Template struct, but adds a Template string property from.. somewhere.

Removing the <xs:simpleType> segment:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
  <xs:element name="template">
    <xs:complexType>
      <xs:sequence>
        <xs:element ref="requests" />
        <xs:element minOccurs="0" ref="responses" />
      </xs:sequence>
      <xs:attribute name="type" use="required" />
    </xs:complexType>
  </xs:element>
  <xs:element name="requests" />
  <xs:element name="responses" />
</xs:schema>

results in a struct that looks more correct:

// Template ...
type Template struct {
	XMLName   xml.Name    `xml:"template"`
	TypeAttr  interface{} `xml:"type,attr"`
	Requests  *Requests   `xml:"requests"`
	Responses *Responses  `xml:"responses"`
}

// Requests ...
type Requests *Requests

// Responses ...
type Responses *Responses

@xuri : It looks like I didn't use the right message format for github to auto-close this issue with my fix in #34. Do you mind closing it since it's now fixed?

I closed this issue, thanks @alexandre-normand.
