/**
*
* 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: {@link XmlList}. However this is redundant since
* {@link XmlList} maps a type to a simple schema type that derives by
* list just as {@link 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>
