Updated Solution - using the schema solution that we were debating. This gets you to your answer:

Sample Schema:

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;schema xmlns="http://www.w3.org/2001/XMLSchema" 
targetNamespace="http://www.example.org/Sport"
xmlns:tns="http://www.example.org/Sport" 
elementFormDefault="qualified"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" 
jaxb:version="2.0"&gt;

&lt;complexType name="sportType"&gt;
 &lt;attribute name="type" type="string" /&gt;
 &lt;attribute name="gender" type="string" /&gt;
&lt;/complexType&gt;

&lt;element name="sports"&gt;
 &lt;complexType&gt;
 &lt;sequence&gt;
 &lt;element name="sport" minOccurs="0" maxOccurs="unbounded"
 type="tns:sportType" /&gt;
 &lt;/sequence&gt;
 &lt;/complexType&gt;
&lt;/element&gt;
</code></pre>



Code Generated

SportType:

<pre><code>package org.example.sport; 

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sportType")
public class SportType {

 @XmlAttribute
 protected String type;
 @XmlAttribute
 protected String gender;

 public String getType() {
 return type;
 }


 public void setType(String value) {
 this.type = value;
 }

 public String getGender() {
 return gender;
 }

 public void setGender(String value) {
 this.gender = value;
 }

}
</code></pre>

Sports:

<pre><code>package org.example.sport;

import java.util.ArrayList;
import java.util.List;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
 "sport"
})
@XmlRootElement(name = "sports")
public class Sports {

 protected List&lt;SportType&gt; sport;

 public List&lt;SportType&gt; getSport() {
 if (sport == null) {
 sport = new ArrayList&lt;SportType&gt;();
 }
 return this.sport;
 }

}
</code></pre>

Output class files are produced by running xjc against the schema on the command line

The correct scheme should be: 

<pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;schema xmlns="http://www.w3.org/2001/XMLSchema"

 type="tns:sportType" /&gt;
