| Associates the MIME type that controls the XML representation of the property.
This annotation is used in conjunction with datatypes such as
{@link Image} or {@link Source} that are bound to base64-encoded binary in XML.
If a property that has this annotation has a sibling property bound to
the xmime:contentType attribute, and if in the instance the property has a value,
the value of the attribute takes precedence and that will control the marshalling. |
