/**
 * <p>Wrap the value inside a CDATA section.  Normally JAXB will escape certain 
 * characters in a string during a marshal operation:
 * <ul>
 * <li>{@code & (as &amp;)}</li>
 * <li>{@code < (as &lt;)}</li>
 * <li>{@code " (as &quot;)}</li>
 * </ul>
 * This means a property foo with string value {@code "1 < 2"} without 
 * {@code @XmlCDATA} will be marshalled as {@code <foo>1 &lt; 2</foo>}. When 
 * {@code @XmlCDATA} is used the content is marshalled as 
 * {@code <foo><![CDATA[1 < 2]]></foo>}.</p>
 * <b>Example</b>
 * <pre>
 * import javax.xml.bind.annotation.XmlRootElement; 
 * import org.eclipse.persistence.oxm.annotations.XmlCDATA;
 * 
 * &#64;XmlRootElement()
 * public class Root {
 *     private String foo;
 *
 *     &#64;XmlCDATA
 *     public String getFoo() {
 *         return foo;
 *     }
 *
 *     public void setFoo(String foo) {
 *         this.foo = foo;
