Unmarshalling complex types using single JAXB annotated class

I have the following xml to be consumed by my application:

<PackageFiles ApplicationGUID="839E9EFD-69C2-430D-B591-B9C8E9812377">
  <Files>
    <File Name="test.jpg" />
  </Files>
</PackageFiles>


To unmarshall with JAXB I've defined the following two classes:

@XmlRootElement(name="PackageFiles")
public class PackageFiles {

    @XmlAttribute(name="ApplicationGUID")
    private String applicationGUID;

    @XmlElementWrapper(name="Files")
    @XmlElement(name="File")
    private List<File> files;
}

@XmlRootElement(name="File")
public class File {

    @XmlAttribute(name="Name")
    private String name;
}


This works great but I was wondering is there a way to annotate the PackageFiles class so that I can eliminate the File class and instead have the Name attribute in the <File ...> element be populated into a List<String> in the PackageFiles class?

If this sort of complication comes up often, you may consider using a Transformer that uses xslt to perform the unmarshalling in a way that you can easily manipulate. Either that or you can make file a public static class inside PackageFiles like so:

public static class File{
    @XmlElement
    private String name;
}

Personally I prefer the xslt method because it's a bit more intuitive and a lot easier to maintain than .java files that are in a constant state of flux.
