public @interface XmlList
Usage
 The @XmlList annotation can be used with the
 following program elements: 
 
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>
 
 @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.
  
@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. @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.
