Used to map a property to a list simple type.
Usage 
 The @XmlList annotation can be used with the following program elements: 
 
  
 JavaBean property 
  
 field 


When a collection property is annotated just with @XmlElement,
each item in the collection will be wrapped by an element.
For example,
@XmlRootElement
class Foo {
    @XmlElement
    List<String> data;
}

would produce XML like this:

<foo>
  <data>abc</data>
  <data>def</data>
</foo>

@XmlList annotation, on the other hand, allows multiple values to be 
represented as whitespace-separated tokens in a single element. For example,
@XmlRootElement
class Foo {
    @XmlElement
    @XmlList
    List<String> data;
}

the above code will produce XML like this:

<foo>
  <data>abc def</data>
</foo>

This annotation can be used with the following annotations: XmlElement, XmlAttribute, XmlValue, XmlIDREF. 

   
 The use of @XmlList with XmlValue while allowed, is redundant since XmlList maps a collection type to a simple schema type that derives by list just as XmlValue would. 
 
   
 The use of @XmlList with XmlAttribute while allowed, is redundant since XmlList maps a collection type to a simple schema type that derives by list just as XmlAttribute would.

 * Used to map a property to a list simple type.
 *
 * <p><b>Usage</b> </p>
 * <p>
 * The {@code @XmlList} annotation can be used with the
 * following program elements: 
 * <ul> 
 *   <li> JavaBean property </li>
 *   <li> field </li>
 * </ul>
 *
 * <p>
 * When a collection property is annotated just with @XmlElement,
 * each item in the collection will be wrapped by an element.
 * For example,
 *
 * <pre>
 * &#64;XmlRootElement
 * class Foo {
 *     &#64;XmlElement
 *     List&lt;String&gt; data;
 * }
 * </pre>
 *
 * would produce XML like this:
 *
 * <pre>{@code
 * <foo>
 *   <data>abc</data>
 *   <data>def</data>
 * </foo>
 * }</pre>
 *
 * &#64;XmlList annotation, on the other hand, allows multiple values to be 
 * represented as whitespace-separated tokens in a single element. For example,
 *
 * <pre>
 * &#64;XmlRootElement
 * class Foo {
 *     &#64;XmlElement
 *     &#64;XmlList
 *     List&lt;String&gt; data;
 * }
 * </pre>
 *
 * the above code will produce XML like this:
 *
 * <pre>{@code
 * <foo>
 *   <data>abc def</data>
 * </foo>
 * }</pre>
 *
 * <p>This annotation can be used with the following annotations:
 *        {@link XmlElement}, 
 *        {@link XmlAttribute},
 *        {@link XmlValue},
 *        {@link XmlIDREF}.
 *  <ul>
 *    <li> The use of {@code @XmlList} with {@link XmlValue} while
 *         allowed, is redundant since  {@link XmlList} maps a
 *         collection type to a simple schema type that derives by
 *         list just as {@link XmlValue} would. </li>
