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>
