JAXB not generating field for redefined attribute - jaxb

Question

I have an xsd that redefines a complex type to add a sequence:
<xs:redefine>
<xs:complexType name="data-extension.type">
<xs:complexContent mixed="true">
<xs:extension base="data-extension.type">
<xs:sequence>
<xs:any minOccurs="0" maxOccurs="unbounded" processContents="strict"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:redefine>
However when I generate the code for my xsd using JAXB, the DataExtensionType class does not has a field for the sequence.
Am I missing something in the xsd or the JAXB generation parameters?
Edit:
This is the generated Java:
/**
* <p>Java class for data-extension.type complex type.
*
* <p>The following schema fragment specifies the expected content contained within this class.
*
* <pre>
* <complexType name="data-extension.type">
* <complexContent>
* <extension base="{http://graphml.graphdrawing.org/xmlns}data-extension.type">
* <redefine>
* <complexType name="data-extension.type">
* <complexContent>
* <restriction base="{http://www.w3.org/2001/XMLSchema}anyType">
* </restriction>
* </complexContent>
* </complexType>
* </redefine>
* <sequence>
* <any processContents='lax' maxOccurs="unbounded" minOccurs="0"/>
* </sequence>
* </extension>
* </complexContent>
* </complexType>
* </pre>
*
*

#XmlType(name = "data-extension.type", namespace = "http://graphml.graphdrawing.org/xmlns")

public class DataExtensionType
extends OriginalDataExtensionType
{
}
The comment suggest the sequence was found during parsing.
I was expecting to see a List<Object> any (or similar) and its getter to be generated. The supper class has a contents field, but its type is String.
Edit 2:
The OriginalData class:
#XmlAccessorType(XmlAccessType.FIELD)
#XmlType(name = "", propOrder = {
"content"
})
#XmlSeeAlso({
DataExtensionType.class
})
#Generated(value = "com.sun.tools.internal.xjc.Driver", date = "2018-03-02T02:29:07+00:00", comments = "JAXB RI v2.2.8-b130911.1802")
public class OriginalDataExtensionType {
#XmlValue
#Generated(value = "com.sun.tools.internal.xjc.Driver", date = "2018-03-02T02:29:07+00:00", comments = "JAXB RI v2.2.8-b130911.1802")
protected String content;
/**

public String getContent() {
return content;
}
/**

#Generated(value = "com.sun.tools.internal.xjc.Driver", date = "2018-03-02T02:29:07+00:00", comments = "JAXB RI v2.2.8-b130911.1802")
public void setContent(String value) {
this.content = value;
}
}
At first I also expected that the contents field would be the sequence.
