There are problems comparing certain durations because of the choice of dateTime values listed in section 3.2.6.2 of the DataTypes spec. The problem arises out of the fact that there is no century year that is a leapyear between 399 BC and AD 399. See http://lists.w3.org/Archives/Public/www-xml-schema- comments/2001AprJun/0017.html
Discussed again at the Feb. 12, 2004 telecon. See: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2004Feb/0066.html Resolved to issue an erratum against 2e noting that algorithm is wrong and will be fixed next time (add requirement against 1.1)
