I'm not sure what you mean by "maintain." There are editors designed to handle XML files.
I looked at some of the slideshow transitions, and not all of them seem to have XML files. "Cell" does, but "timelapse" does not; and some of them have all kinds of stuff besides XML files. Unless Cyberlink opens this up, someone would have to reverse-engineer the whole business.
