/**
* Marks a field/property that its XML form is a uri reference to mime content.
* The mime content is optimally stored out-of-line as an attachment.
*
* A field/property must always map to the {@link DataHandler} class.
*
* <h2>Usage</h2>
* <pre>
* @{@link XmlRootElement}
* class Foo {
* @{@link XmlAttachmentRef}
* @{@link XmlAttribute}
* {@link DataHandler} data;
*
* @{@link XmlAttachmentRef}
* @{@link XmlElement}
* {@link DataHandler} body;
* }
* </pre>
* The above code maps to the following XML:
* <pre><xmp>
* <xs:element name="foo" xmlns:ref="http://ws-i.org/profiles/basic/1.1/xsd">
* <xs:complexType>
* <xs:sequence>
* <xs:element name="body" type="ref:swaRef" minOccurs="0" />
* </xs:sequence>
* <xs:attribute name="data" type="ref:swaRef" use="optional" />
* </xs:complexType>
* </xs:element>
* </xmp></pre>
*
* <p>
