I found additional confirmation that the 2000 version of ISO 8601 does,
indeed, allow the year 0000.  I don't know what it maps to in terms on
AD and BC because AD 1 == 0001 and BC 1 == -0001.  Should we discuss as
a possible errata item.

	     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?
