There is no ‘official’ solution for saving your subclip mark up made in XDCAM Transfer.
There are some possibilities, however.
If you are working only with Macs:
(1) You could save the database created by XDCAM Transfer. The path can be found by looking on the Cache tab in the preferences. You should find three folders there. Save the one containing the database and the one containing the thumbnails to the General folder of your disc. Don’t bother saving the proxies because XDCAM Transfer can make those again (‘Fetch Proxies’ from the disc’s context menu).
On the other machine, copy the database and thumbnail folders out of the General folder into a folder somewhere sensible and then change XDCAM Transfer’s Cache path to point to there. You should then be able to see your mark up just as it was.
(2) Alternatively, you can use the Applescripts posted on this thread to save all your logging to a file and then retrieve it again.

If you want to see subclips made with XDCAM Transfer in Windows, then I’m not really sure. It’s easy enough to write the logging to a file (e.g Robert’s script) but then you need something on Windows that can show it. There may be a possibility with the PDZ-1 software but I don’t have much experience with it myself and I suspect this would be non-trivial.
