Andrew,

straw man:

@XmlType
public class Feed {
  @XmlElement public String author;
  @XmlAnyElement @XmlElementRef public List<Object> extensions;
}

JaxbContext.create(Feed.class).newUnmarshaller().unmarshal(
  <feed><author>Matthias</author><liaison>CoreMedia</liaison></feed>,
Feed.class);

would unmarshal into:

  Feed {
    author = "Matthias"
    extensions = [ org.w3c.dom.Element "liaison" { org.w3c.dom.Text "CoreMedia" } ]
  }

So far so great. Now you realise that "liaison" is a "standard" element for your application. You go ahead and add

@XmlRootElement(name="liaison")
@XmlType(name="liaison")
public class Liaison {
  @XmlValue
  public String value;
}

and make it known to the context: JaxbContext.create(Feed.class, Laison.class) ...

et voila: it unmarshals into

  Feed {
    author = "Matthias"
    extensions = [ Liaison { value="CoreMedia" } ]
  }


Does that help?
Matthias
