Am I remembering it correctly that the ISO:8601 handles
duration/periods/intervals absolutely fine, but that it is the W3C datatype
which doesn't?

I think ISO 8601 allows:

   1. Start and end, such as 2006-05-01T13:00:00Z/2006-05-11T15:30:00Z
   2. Start and duration, such as 2006-03-01T13:00:00Z/P1Y2M10DT2H30M
   3. Duration and end, such as P1Y2M10DT2H30M/2006-05-11T15:30:00Z
   4. Duration only, such as P1Y2M10DT2H30M

But that these aren't catered for in the W3C datatype.  (Which is a shame.)
