http://www.w3.org/TR/NOTE-datetime , and http://en.wikipedia.org/wiki/ISO_8601
seem to indicate that a four-digit year with leading zeroes is required. To
quote from the "General principles" section in the latter reference:
"Each date and
time value has a fixed number of digits that must be padded with leading zeros".
