One Interesting Way to Use FileMaker XML Files

Claris introduced a new feature in version 18 of the FileMaker Platform called Save a Copy as XML. You can find this command within the Tools menu if you have the "use advanced tools" option enabled in the FileMaker desktop application's Preferences section. With this menu command, Claris gives us a window into each of our custom apps' inner workings, as well as a way to more easily document even the most complex ones.
