That (with the hyphens in dates and colons in times) is actually not the 
basic, but the extended format. I have only ever read the 2000 version, 
so please CMIIW, but AFAIK the 2004 edition basically removes many of 
the truncated/implied and basic formats in favor of the more 
human-friendly extended format, which many specificators favored anyhow, 
like for instance <http://www.w3.org/TR/NOTE-datetime>. I think the 
literal T in date-times was also removed in favor of the space, which 
previously was only second choice. That W3C Note sadly does not endorse 
fractional time (23,55 = 23:30:30) except for seconds, nor the week and 
day based calendars (2005-W28-1, 2005-123), which ISO 8601:2004 retains. 
Durations are cumbersome.
