Arising out of a discussion with CC: The intended use of <choice>/<orig>/<reg> in the original transcriptions of the engravings is to restore normal contemporary usage, while the modern transcription is a full modernization. However, there are instances of <choice>/<orig>/<reg> which are used to replace long s with short s (dating back to when we had no modernizations), so these are inconsistent with our policy, and we should get rid of them. I might be able to do this entirely mechanically -- in the case of any regularization where the only difference is between long and short s, I can simply replace the entire <choice> element with the contents of <orig>; while for every regularization where a long s exists in the <orig> but other things are also regularized in the <reg>, I can add an attribute we can use temporarily to find and manually fix them. This is now on my task list.
