37 * Maps a Java type to a simple schema built-in type.
38 *
39 * <p> <b>Usage</b> </p>
40 * <p>
41 * <tt>@XmlSchemaType</tt> annotation can be used with the following program
42 * elements:
43 * <ul>
44 * <li> a JavaBean property </li>
45 * <li> field </li>
46 * <li> package</li>
47 * </ul>
48 *
49 * <p> <tt>@XmlSchemaType</tt> annotation defined for Java type
50 * applies to all references to the Java type from a property/field.
51 * A <tt>@XmlSchemaType</tt> annotation specified on the
52 * property/field overrides the <tt>@XmlSchemaType</tt> annotation
53 * specified at the package level.
54 *
55 * <p> This annotation can be used with the following annotations:
56 * {@link XmlElement}, {@link XmlAttribute}.
57 * <p>
58 * <b>Example 1: </b> Customize mapping of XMLGregorianCalendar on the
59 * field.
60 *
61 * <pre>
62 * //Example: Code fragment
63 * public class USPrice {
64 * @XmlElement
65 * @XmlSchemaType(name="date")
66 * public XMLGregorianCalendar date;
67 * }
68 *
69 * <!-- Example: Local XML Schema element -->
70 * <xs:complexType name="USPrice"/>
71 * <xs:sequence>
72 * <xs:element name="date" type="xs:date"/>
73 * </sequence>
74 * </xs:complexType>
75 * </pre>
76 *
77 * <p> <b> Example 2: </b> Customize mapping of XMLGregorianCalendar at package
78 * level </p>
79 * <pre>
80 * package foo;
81 * @javax.xml.bind.annotation.XmlSchemaType(
82 * name="date", type=javax.xml.datatype.XMLGregorianCalendar.class)
