| <div class="block"><p><b>XmlJoinNode</b> is used in conjunction with <code>XmlKey</code> to specify a reference mapping. This is similar |
| to XmlID and XmlIDREF but allows for keys that are of types other than ID. When used with <code>XmlJoinNodes</code> can |
| be used to allow composite keys. The referencedXmlPath must match the xpath of a field on the target class that has |
| been annotated with either XmlID or XmlKey. |
| |
| <p><b>Example:</b> |
| <pre> |
| @XmlRootElement |
| @XmlAccessorType(XmlAccessType.FIELD) |
| public class Employee { |
| |
| @XmlKey |
| public String id; |
| |
| public String department; |
