Yes, I see. Originally we were only going to allow ? at the end of the string, and we subsequently decided to allow it internally, so I marked up the
"Century, year, month, day, hour, minute, second" section to allow ? and ~ internally. Instead I should have expanded "Uncertain or Approximate" section andleft the first one alone. I'll fix that. Thanks.
