ohair@286 36 * <p>
ohair@286 37 * A container for multiple @{@link XmlElement} annotations.
ohair@286 38 *
ohair@286 39 * Multiple annotations of the same type are not allowed on a program
ohair@286 40 * element. This annotation therefore serves as a container annotation
ohair@286 41 * for multiple &#64;XmlElements as follows:
ohair@286 42 *
ohair@286 43 * <pre>
ohair@286 44 * &#64;XmlElements({ @XmlElement(...),@XmlElement(...) })
ohair@286 45 * </pre>
ohair@286 46 *
ohair@286 47 * <p>The <tt>@XmlElements</tt> annnotation can be used with the
ohair@286 48 * following program elements: </p>
ohair@286 49 * <ul>
ohair@286 50 * <li> a JavaBean property </li>
ohair@286 51 * <li> non static, non transient field </li>
ohair@286 52 * </ul>
ohair@286 53 *
ohair@286 54 * This annotation is intended for annotation a JavaBean collection
ohair@286 55 * property (e.g. List).
ohair@286 56 *
ohair@286 57 * <p><b>Usage</b></p>
ohair@286 58 *
ohair@286 59 * <p>The usage is subject to the following constraints:
ohair@286 60 * <ul>
ohair@286 61 * <li> This annotation can be used with the following
ohair@286 62 * annotations: @{@link XmlIDREF}, @{@link XmlElementWrapper}. </li>
ohair@286 63 * <li> If @XmlIDREF is also specified on the JavaBean property,
ohair@286 64 * then each &#64;XmlElement.type() must contain a JavaBean
ohair@286 65 * property annotated with <tt>&#64;XmlID</tt>.</li>
ohair@286 66 * </ul>
ohair@286 67 *
ohair@286 68 * <p>See "Package Specification" in javax.xml.bind.package javadoc for
ohair@286 69 * additional common information.</p>
