duplicate element not is detected with maven jaxb/jaxb2 plugin - xsd

Question

I'm using maven-jaxb-plugin and maven-jaxb2-plugin to compile a xsd file that has two elements with same name, but the code compiles without throws an error. The generated class don't have the co-related properties. See the generated class:
...
* <element name="elementName" type="{http://namespace}typeElementName"/>
* <element name="elementName" type="{http://namespace}typeElementName"/>
public class TypeNameType {
#XmlElementRefs({
#XmlElementRef(name = "elementName", namespace = "http://namespace", type = JAXBElement.class)
})
protected List<JAXBElement<? extends Serializable>> content;
public List<JAXBElement<? extends Serializable>> getContent() {
if (content == null) {
content = new ArrayList<JAXBElement<? extends Serializable>>();
}
return this.content;
}
}
and XSD:
<schema elementFormDefault="qualified"
targetNamespace="http://namespace"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://namespace">
<complexType name="typeNameType">
<sequence>
<element minOccurs="1" maxOccurs="1" name="elementName" type="string" />
<element minOccurs="1" maxOccurs="1" name="elementName" type="string" />
</sequence>
</complexType>
</schema>
Can anybody help me with this issue?
Tks!

Validating a bunch of xml files and xsd files as well, can be done by the xml-maven-plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xml-maven-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<goals>
<goal>validate</goal>
</goals>
</execution>
</executions>
<configuration>
<validationSets>
<validationSet>
<dir>src/main/xsd</dir>
<systemId>http://www.w3.org/2001/XMLSchema.xsd</systemId>
</validationSet>
</validationSets>
</configuration>
<plugin>
Havin all your xsd files below src/main/xsd the plugin will validate them against http://www.w3.org/2001/XMLSchema.xsd by runing mvn xml:validate. You should download the XMLSchema.xsd to your project to make validation faster and to skip the request to w3.org.
