Regarding WORDSNET-17087, unfortunately the implementation of the fix of this issue has been postponed till a later date (currently no estimates are available). We will inform you via this thread as soon as this issue is resolved or any estimates are available. We apologize for any inconvenience.
As a workaround maybe it will be possible to embed attachments to Aspose.Words generated PDF output via third-party PDF editing tool (like Aspose.PDF for Java). You could probably get the attachment data and position from the Aspose.Words DOM and then create a File Attachment Annotation in PDF output with Aspose.PDF. If you are interested in such workaround, we probably could investigate it further and provide a code sample.
