import static java.lang.annotation.ElementType.*;
import java.lang.annotation.Retention;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.Target;

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 DataHandler class. 
Usage
@XmlRootElement class Foo { @XmlAttachmentRef @XmlAttribute DataHandler data; @XmlAttachmentRef @XmlElement DataHandler body; } 
The above code maps to the following XML:

<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>


The above binding supports WS-I AP 1.0 WS-I Attachments Profile Version 1.0.
