/**
 *Purpose: This annotation is used in conjunction with an XmlElements annotation to
 * specify an XmlPath for each of the XmlElement annotations in the XmlElements.
 * The number of XmlPath annotations must be the same as the number of XmlElement annotations
 * and the order must be the same.
 *
 * 
Example:

 * 
 *  @XmlRootElement(name="customer")

 *  public class Customer {

 *     ...

 *     @XmlElements({@literal {@XmlElement(type=String.class), @XmlElement(type=Integer.class)}})

 *     @XmlPaths({@literal {@XmlPath("choice-element/string/text()"), @XmlPath("choice-element/integer/text()")}})

 *     public Object choice

 *     ...

 *  }


 * Will create the following Schema:

 *
 * 
 *    ...
 *    <xsd:choice>
 *       <xsd:element name="choice-element" minOccurs="0">
 *          <xsd:complexType>
 *             <xsd:choice>
 *                <xsd:element name="string" type="xsd:string" minOccurs="0"/>
 *                <xsd:element name="integer" type="xsd:int" minOccurs="0"/>
 *             </xsd:choice>
 *          </xsd:complexType>
 *       </xsd:element>
 *    </xsd:choice>
 *    ...
 *
