When processing a property tagged with an XmlElementRef annotation, the EclipseLink MappingsGenerator will create an XmlChoiceObjectMapping. In the case that the target of this XmlElementRef is a JAXBElement<byte[]>, the choice mapping will create an XMLDirectMapping to handle this under the covers. Unfortunately an XMLDirectMapping can only handle inline binary from byte[] and not attachments.

In order to handle attachments in this case XMLChoiceObjectMapping needs to support nested XMLBinaryDataMappings or MappingsGenerator needs to generate a different mapping in this case.
