Which version of 8601 did you check?
The 1998 version says in section 5.2.1
"In the Gregorian calendar consecutive calendar years consecutive years
are identified by consecutive numbers, except for the calendar year
[-0001] which is followed by the year [0001]"
In the 2000 version, I only found a note that said in section
that in the prolaptic [sic] Gregorian calendar the year 0000  is a leap
In which section did you see the year 0000 mentioned?

	     I just saw a copy of ISO 8601:2000.  I was surprised to
discover that it defines 0000 to be a valid year, unlike the
specification of dateTime in the "XML Schema:  Datatypes" recommendation
[1].  I gather that in ISO 8601:2000, the year 0000 is roughly
equivalent to what people usually refer to as 1BC, and is a leap year. 
	     Should dateTime follow ISO 8601:2000 in this respect?
