Hi Thomas, If you edit a file with an .xml suffix, it will be parsed as XML. This error message should only appear if​ you run your editor file as query (via the PLAY button or Ctrl+Enter). If your experience differs, feel free to give me more information on how you proceed. Maybe it would be less confusing if we disallowed query execution for all named files that have no XQuery suffix?
