For when populating some cases, ISO8601 'R' notation could be used. E.g. "R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M".
Update documentation re complex and simple cases.
Could even use cron expressions or similar.
I agree - let's make timing optional for 1.0.4.
Looks reasonable to me - you could correct two typos:
For example, 5 repititions of the period '10 days' starting on 01 march 2008 is `"R5/2008-03-01T13:00:00Z/P10D"`.
The Action_archteype_id_valid invariant
Both typos corrected - they will flow through in the next upload.
Good that timing is made optional.
