JAXB ClassCastException in SOAP handler

Issue

Given the following XSD:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="me">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="name" type="xs:string"/>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

I want to process the following SOAP header in a handler:

<soapenv:Header>
 <custom:me xmlns:custom="http://ws.examples.jboss.com/">
  <name>Kyle</name>
 </custom:me>
</soapenv:Header>

Like so:

JAXBContext jc = JAXBContext.newInstance("com.jboss.examples.ws"); //custom package name
Unmarshaller u = jc.createUnmarshaller();
String uri = "http://ws.examples.jboss.com/";
SOAPHeader header = msgContext.getMessage().getSOAPHeader();
Node me = header.getElementsByTagNameNS(uri,"me").item(0);
MyObject headerType = (MyObject)u.unmarshal(me);

But I receive the following exception:

java.lang.ClassCastException: javax.xml.bind.JAXBElement cannot be cast to com.jboss.examples.ws.MyObject
