Re: [UR-WG] Comment on duration format for WallDuration and CpuDuration

ISO8601 allows to set the start date for a given period like in 2005-08-09T18:31:42P6M4DT12H30M17S which are 5 months, 4 days, 12hours 30 minutes and 17 seconds after 2005-08-09 18:31:42. So in principle there is no problem with using the ISO format.

That's not a duration, but rather a time period (which is effectively an anchored duration). Supporting that would take deep schema hacking (modifying facets of simple types IIRC) unfortunately, and what's worse, would not be well supported by tooling. Donal.
