::::::::Thanks for taking time out to drop by, Ymblanter. Unless  still has profound objections, I'm leaving this on the backburner for the moment. There are so many pages that need fleshing out and a good tidy that I'm not going to touch it until or if I have time. I've pointed him in the direction of some of some source info and would suggest that it's highly likely that the editor/contributor who added this info may no longer be active here. Finding out what the interpretations are, as you suggest, merely a matter of a little research.
