In addition to being able to manage map attachments in the UI or with web services, ADMIN and KHUB_ADMIN users can also manage map attachments asychronously by uploading a control file after publishing DITA or FTML content.
Depending on the type of publication, the process is as follows:
For DITA publications, the control file must be uploaded through the DITA PaF.
For FTML publications, the control file must be uploaded through the FTML PaF.
Map attachments added with a control file will have no effect on those added manually in the interface, unless the originId or khubId is used to update a map attachment.
