/**
 * INTERNAL:
 * Purpose:Provide an implementation of the TopLink OX XMLAttachmentMarshaller
 * interface that wraps an implementation of the JAXB AttachmentMarshaller interface.
 * 
Responsibilities:

 * Implement the XMLAttachmentMarshaller interface
 * Adapt events from the TopLink OX Attachment API to the JAXB 2.0 Attachment API
 * 
 * This class allows TopLink OXM to do attachment marshalling callback events to a JAXB
 * 2.0 Listener without adding a dependancy on JAXB 2.0 into core TopLink. The Adapter class
 * wraps a javax.xml.bin.attachment.AttachmentMarshaller and passes on the events as they're raised
 *
 * @see javax.xml.bind.attachment.AttachmentMarshaller
 * @see org.eclipse.persistence.oxm.attachment.XMLAttachmentMarshaller
 * @since Oracle TopLink 11.1.1.0.0
