/**
 * 
 * Annotate a JavaBean multi-valued property to support mixed content.
 *
 * 

 * The usage is subject to the following constraints:
 * 

 *    can be used with @XmlElementRef, @XmlElementRefs or @XmlAnyElement
 * 
 * 
 * The following can be inserted into @XmlMixed annotated multi-valued property
 * 

 * XML text information items are added as values of java.lang.String.
 * Children element information items are added as instances of
 * {@link JAXBElement} or instances with a class that is annotated with
 * @XmlRootElement.
 * Unknown content that is not be bound to a JAXB mapped class is inserted
 * as {@link Element}. (Assumes property annotated with @XmlAnyElement)
 * 
 *
 * Below is an example of binding and creation of mixed content.
 *  *  <!-- schema fragment having  mixed content -->
 *  <xs:complexType name="letterBody" mixed="true">
 *    <xs:sequence>
 *	<xs:element name="name" type="xs:string"/>
 *	<xs:element name="quantity" type="xs:positiveInteger"/>
 *	<xs:element name="productName" type="xs:string"/>
 *	<!-- etc. -->
 *    </xs:sequence>
 *  </xs:complexType>
 *  <xs:element name="letterBody" type="letterBody"/>
 * 
 * // Schema-derived Java code: 
 * // (Only annotations relevant to mixed content are shown below, 
 * //  others are ommitted.)

 * 	JAXBElement<BigInteger> createLetterBodyQuantity(BigInteger value);
 * 	JAXBElement<String>     createLetterBodyProductName(String value);
 *      // type instance factory
 * 	LetterBody> createLetterBody();
 * }
 * 
 *  * public class LetterBody {
 * 	// Mixed content can contain instances of Element classes
 * 	// Name, Quantity and ProductName. Text data is represented as
 *	// java.util.String for text.
 *	@XmlMixed 
 * 	@XmlElementRefs({
 *		@XmlElementRef(name="productName", type=JAXBElement.class),
 *		@XmlElementRef(name="quantity", type=JAXBElement.class),
 *		@XmlElementRef(name="name", type=JAXBElement.class)})
 *	List getContent(){...}
 * }
 * 
 * The following is an XML instance document with mixed content
 *  * <letterBody>
 * Dear Mr.<name>Robert Smith</name>
 * Your order of <quantity>1</quantity> <productName>Baby
 * Monitor</productName> shipped from our warehouse. ....
 * </letterBody>
 * 
 * that can be constructed using following JAXB API calls.
 *  * LetterBody lb = ObjectFactory.createLetterBody();
 * JAXBElement<LetterBody> lbe = ObjectFactory.createLetterBody(lb);
 * List gcl = lb.getContent();  //add mixed content to general content property.
 * gcl.add("Dear Mr.");  // add text information item as a String.
 * 
 * // add child element information item
 * gcl.add(ObjectFactory.createLetterBodyName("Robert Smith"));
 * gcl.add("Your order of "); // add text information item as a String
 * 
 * // add children element information items
 * gcl.add(ObjectFactory.
 * 	 		createLetterBodyQuantity(new BigInteger("1")));
 * gcl.add(ObjectFactory.createLetterBodyProductName("Baby Monitor"));
 * gcl.add("shipped from our warehouse");  // add text information item
