Not sure if this is better in here or as a bug, since i'm not sure it's intentional or not and it may simply be that the XML needs an additional record that the community can figure out, which has happened in the past when we thought this feature was removed. I've put it in here instead of a bug in the hope other users know a workaround.
With FM23 when you create a file in the Editor and use File > Export to get an XML file you can no longer put this file in the editor data folder and use it when starting a new game. Only fmf files are recognised and shown with checkboxes under the "Editor Data Files" heading when starting a new game.
XML files are necessary when creating editor files collaboratively.
This feature has already been removed in the past, in 2015, and was bought back after community feedback.
You can read that old thread to get a number of opinions of why this ability is valuable to the community.
I've attached an example of Ralph Hasenhüttl being released here and i've embedded the xml in this comment as well:
