</li>
</ul>
<p>Other important changes and updates include:</p>
<ul>
<li>
Behavior of @XmlID and @XmlValue annotations has been updated to be JAXB 2.2 RI compatible.
Fields annotated with @XmlID must be of type String, classes which contain field with @XmlValue annotation must not extend other type than java.lang.Object.
To provide backward compatibility with EclipseLink 2.5.0, annotations @XmlIDExtension and @XmlValueExtension were introduced.
</li>
<li>
Annotations @XmlElementNillable and @XmlNullPolicy are supported in both ElementType.TYPE and ElementType.PACKAGE targets, to enable configuration of @XmlElement
nillable parameter and runtime null policy at package level.
</li>
</ul>
