Working with poorly designed XML with JAXB

I am currently working on replacing an obsolete system with JAXB and I am having trouble parsing XML. The number one requirement for a system is that it must be a replacement, so I cannot change the XML format. Below is the XML section that is causing me problems.

<xx>
    <s1>
        <X>-9999</X>
        <Y>-9999</Y>
    </s1>
    <s2>
        <X>-9999</X>
        <Y>-9999</Y>
   </s2>
</xx>

The problem with XML is that all s # objects are exact and can contain up to 256 of them. Is there a way in JAXB to annotate such a tag, or do I need to create 256 separate annotations? Any help would be most appreciated.

Here is the java code for the xx object. Note: the object was originally programmed with the understanding that there will be only 2 s # objects, but this has changed.

@XmlRootElement(name="xx")

public class XMLXx implements Serializable {

    private static final long serialVersionUID = 4064597372833234503L;

    private XMLSite siteOne;
    private XMLSite siteTwo;

    @XmlElement(name="s1")
    public XMLSite getSiteOne() {
        return siteOne;
    }

    public void setSiteOne(XMLSite s1) {
        this.siteOne = s1;
    }

    @XmlElement(name="s2")
    public XMLSite getSiteTwo() {
        return siteTwo;
    }

    public void setSiteTwo(XMLSite s2) {
        this.siteTwo = s2;
    }
}

And here is the XMLSite object:

public class XMLSite implements Serializable {

    private static final long serialVersionUID = -4374405403222014476L;

    private Integer x;
    private Integer y;

    @XmlElement(name="X")
    public Integer getX() {
        return x;
    }

    public void setX(Integer x) {
        this.x = x;
    }

    @XmlElement(name="Y")
    public Integer getY() {
        return y;
    }

    public void setY(Integer y) {
        this.y = y;
    }
}

@XmlRootElement(name="xx")
public class XMLXx implements Serializable {

    private static final long serialVersionUID = 4064597372833234503L;

    private List<XMLSite> sites;

    @XmlElement(name="s")
    public List<XMLSite> getSites() {
        return sites;
    }

    public void setSites(List<XMLSite> sites) {
        this.sites = sites;
    }

            return localName;
