/**
* <p><b>XmlJoinNodes</b> is a holder for multiple {@code XmlJoinNode} annotations. This is used to specify the source to target
* associations in a reference mapping with multiple keys. XmlJoinNodes will contain one XmlJoinNode for each key. The
* targets of the individual XmlJoinNode annotations must be annotated with either {@code XmlID} or {@code XmlKey}.
*
* <p><b>Example:</b>
* <pre>
* @XmlRootElement
* @XmlAccessorType(XmlAccessType.FIELD)
* public class Employee {
*
* @XmlKey
* public String id;
*
* @XmlKey
* public String department;
*
* @XmlJoinNodes({
* @XmlJoinNode(xmlPath="manager/id/text()", referencedXmlPath="id/text()"),
* @XmlJoinNode(xmlPath="manager/dept/text()", referencedXmlPath="department/text()")
* })
* public Employee manager;
