I believe that this form is allowed by the schema spec. Section 3.3.24.1 says To accommodate year values outside the range from 0 to 9999, additional digits can be added to the left of this representation and an preceding "-" is allowed. I believe there are two typos here (there is no year 0 in the Gregorian calendar, so the range should be 1-9999, and for 'an' read 'a'), but the phrase about the preceding minus sign is not a typo. Personally, I agree that there should be a note pointing out that '0000' is not a valid year; otherwise, too many implementors will get it wrong. -C. M. Sperberg-McQueen
