The 1st or 2nd draft of Datatypes that I wrote had type for EVERYTHING in ISO 
8601, include the week types and the full range of durations.  My memory is a 
little sketchy about matters that far back and I'm not sure if those were just 
editor's drafts or if we published them.  I also don't remember why the WG 
decided to take out those parts of 8601.

Poking around a bit, I do see that xs:timePeriod was in the Jun 04 1999 WD [1].
