javax.xml.bind.annotation

## Annotation Type XmlValue

-     @Retention(value=RUNTIME)
      @Target(value={FIELD,METHOD})
      public @interface XmlValue

  Enables mapping a class to a XML Schema complex type with a simpleContent or a XML Schema simple type.

  Usage:

  The `@XmlValue` 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 usage constraints:
  - At most one field or property can be annotated with the `@XmlValue` annotation.
  - `@XmlValue` can be used with the following annotations: `XmlList`. However this is redundant since `XmlList` maps a type to a simple schema type that derives by list just as `XmlValue` would.
  - If the type of the field or property is a collection type, then the collection item type must map to a simple schema type.
  - If the type of the field or property is not a collection type, then the type must map to a XML Schema simple type.

  If the annotated JavaBean property is the sole class member being mapped to XML Schema construct, then the class is mapped to a simple type. If there are additional JavaBean properties (other than the JavaBean property annotated with `@XmlValue` annotation) that are mapped to XML attributes, then the class is mapped to a complex type with simpleContent.

  Example 1: Map a class to XML Schema simpleType

           // Example 1: Code fragment
           public class USPrice {
               @XmlValue
               public java.math.BigDecimal price;
           }

           <!-- Example 1: XML Schema fragment -->
           <xs:simpleType name="USPrice">
             <xs:restriction base="xs:decimal"/>
           </xs:simpleType>

  Example 2: Map a class to XML Schema complexType with with simpleContent.

         // Example 2: Code fragment
         public class InternationalPrice {
             @XmlValue
             public java.math.BigDecimal price;

             @XmlAttribute
             public String currency;
         }

         <!-- Example 2: XML Schema fragment -->
         <xs:complexType name="InternationalPrice">
           <xs:simpleContent>
             <xs:extension base="xs:decimal">
               <xs:attribute name="currency" type="xs:string"/>
             </xs:extension>
           </xs:simpleContent>
         </xs:complexType>
