    1.40 + * Maps a JavaBean property to a XML element derived from property name.
    1.41 + *
    1.42 + * <p> <b>Usage</b> </p>
    1.43 + * <p>
    1.44 + * <tt>@XmlElement</tt> annotation can be used with the following program
    1.45 + * elements:
    1.46 + * <ul>
    1.47 + *   <li> a JavaBean property </li>
    1.48 + *   <li> non static, non transient field </li>
    1.49 + *   <li> within {@link XmlElements}
    1.50 + * <p>
    1.51 + *
    1.52 + * </ul>
    1.53 + *
    1.54 + * The usage is subject to the following constraints:
    1.55 + * <ul>
    1.56 + *   <li> This annotation can be used with following annotations:
    1.57 + *            {@link XmlID},
    1.58 + *            {@link XmlIDREF},
    1.59 + *            {@link XmlList},
    1.60 + *            {@link XmlSchemaType},
    1.61 + *            {@link XmlValue},
    1.62 + *            {@link XmlAttachmentRef},
    1.63 + *            {@link XmlMimeType},
    1.64 + *            {@link XmlInlineBinaryData},
    1.65 + *            {@link XmlElementWrapper},
    1.66 + *            {@link XmlJavaTypeAdapter}</li>
    1.67 + *   <li> if the type of JavaBean property is a collection type of
    1.68 + *        array, an indexed property, or a parameterized list, and
    1.69 + *        this annotation is used with {@link XmlElements} then,
    1.70 + *        <tt>@XmlElement.type()</tt> must be DEFAULT.class since the
    1.71 + *        collection item type is already known. </li>
    1.72 + * </ul>
    1.73 + *
    1.74 + * <p>
    1.75 + * A JavaBean property, when annotated with @XmlElement annotation
    1.76 + * is mapped to a local element in the XML Schema complex type to
    1.77 + * which the containing class is mapped.
