ohair@286 35 * <p>
ohair@286 36 * Maps a JavaBean property to a XML attribute.
ohair@286 37 *
ohair@286 38 * <p> <b>Usage</b> </p>
ohair@286 39 * <p>
ohair@286 40 * The <tt>@XmlAttribute</tt> annotation can be used with the
ohair@286 41 * following program elements:
ohair@286 42 * <ul>
ohair@286 43 * <li> JavaBean property </li>
ohair@286 44 * <li> field </li>
ohair@286 45 * </ul>
ohair@286 46 *
ohair@286 47 * <p> A static final field is mapped to a XML fixed attribute.
ohair@286 48 *
ohair@286 49 * <p>See "Package Specification" in javax.xml.bind.package javadoc for
ohair@286 50 * additional common information.</p>
ohair@286 51 *
ohair@286 52 * The usage is subject to the following constraints:
ohair@286 53 * <ul>
ohair@286 54 * <li> If type of the field or the property is a collection
ohair@286 55 * type, then the collection item type must be mapped to schema
ohair@286 56 * simple type.
ohair@286 57 * <pre>
ohair@286 58 * // Examples
ohair@286 59 * &#64;XmlAttribute List&lt;Integer> items; //legal
ohair@286 60 * &#64;XmlAttribute List&lt;Bar> foo; // illegal if Bar does not map to a schema simple type
ohair@286 61 * </pre>
ohair@286 62 * </li>
ohair@286 63 * <li> If the type of the field or the property is a non
ohair@286 64 * collection type, then the type of the property or field
ohair@286 65 * must map to a simple schema type.
ohair@286 66 * <pre>
ohair@286 67 * // Examples
ohair@286 68 * &#64;XmlAttribute int foo; // legal
ohair@286 69 * &#64;XmlAttribute Foo foo; // illegal if Foo does not map to a schema simple type
ohair@286 70 * </pre>
ohair@286 71 * </li>
ohair@286 72 * <li> This annotation can be used with the following annotations:
ohair@286 73 * {@link XmlID},
ohair@286 74 * {@link XmlIDREF},
ohair@286 75 * {@link XmlList},
ohair@286 76 * {@link XmlSchemaType},
ohair@286 77 * {@link XmlValue},
ohair@286 78 * {@link XmlAttachmentRef},

ohair@286 80 * {@link XmlInlineBinaryData},
ohair@286 81 * {@link javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter}.</li>
ohair@286 82 * </ul>
ohair@286 83 * </p>
ohair@286 84 *
ohair@286 85 * <p> <b>Example 1: </b>Map a JavaBean property to an XML attribute.</p>
