/**
* 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>def
* </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
* </foo>
*
*
* This annotation can be used with the following annotations:
* {@link XmlElement},
* {@link XmlAttribute},
* {@link XmlValue},
* {@link XmlIDREF}.
*
* - The use of @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.
*
* - The use of @XmlList with {@link XmlAttribute} while
* allowed, is redundant since {@link XmlList} maps a
* collection type to a simple schema type that derives by
* list just as {@link XmlAttribute} would.
