@Retention(value=RUNTIME) @Target(value={FIELD,METHOD}) public @interface XmlID
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 @XmlID and @XmlIDREF together allow a customized mapping of a JavaBean property's type by containment or reference.
Usage
The @XmlID annotation can be used with the following program elements:See "Package Specification" in javax.xml.bind.package javadoc for additional common information.
The usage is subject to the following constraints:Example: Map a JavaBean property's type to xs:ID
    // Example: code fragment
    public class Customer {
        @XmlAttribute
        @XmlID
        public String getCustomerID();
        public void setCustomerID(String id);
        .... other properties not shown
    }
    <!-- Example: XML Schema fragment -->
    <xs:complexType name="Customer">
      <xs:complexContent>
        <xs:sequence>
          ....
        </xs:sequence>
        <xs:attribute name="customerID" type="xs:ID"/>
      </xs:complexContent>
    </xs:complexType>
