LVGL has begun relicensed and removed the lv_xml module from and moved it under LVGL Pro
More discussion here: https://github.com/lvgl/lvgl/issues/9663
Have to read the commit history on this one to see the order things happened - lv_xml appears to have started as MIT licensed with everything else, then license changed last fall, then it was removed with claims of always-been-proprietary.
