/**
*
* Maps a JavaBean property to XML ID.
*
*
* To preserve referential integrity of an object graph across XML
* serialization followed by a XML deserialization, requires an object
* reference to be marshalled by reference or containment
* appropriately. Annotations {@code @XmlID} and {@code @XmlIDREF}
* together allow a customized mapping of a JavaBean property's
* type by containment or reference.
*
*
Usage
* The {@code @XmlID} annotation can be used with the following
* program elements:
*
* - a JavaBean property
* - non static, non transient field
*
*
* See "Package Specification" in javax.xml.bind.package javadoc for
* additional common information.
*
* The usage is subject to the following constraints:
*
* - At most one field or property in a class can be annotated
* with {@code @XmlID}.
* - The JavaBean property's type must be {@code java.lang.String}.
* - The only other mapping annotations that can be used
* with {@code @XmlID}
* are: {@code @XmlElement} and {@code @XmlAttribute}.
*
*
* Example: Map a JavaBean property's type to {@code xs:ID}
*
* // Example: code fragment
* public class Customer {
* @XmlAttribute
* @XmlID
* public String getCustomerID();
* public void setCustomerID(String id);
* .... other properties not shown
* }
* {@code
*
*
*
*
*
* ....
*
*
*
* }
