Analog to getodk/build#284
This one is in the "hard" basket for sure. Audit settings in the XML are in the form metadata but need to become a question in the "survey" sheet of the XLSForm. The existing plumbing separates form metadata (like instance name - gen-settings) from form questions (convert-question). I don't see a way to add audit that doesn't change existing plumbing considerably.
Any ideas or pointers, @issa-tseng?
