[poe] Definition of odrl:delayPeriod

simonstey has just created a new issue for https://github.com/w3c/poe:

== Definition of odrl:delayPeriod ==
The description of Example 27 in Section 3.8.1 Constraint Relations 
[1] states:

> The Policy below shows a Permission to distribute photos in which 
the first constraint (the event "football/game/2017" has passed) is 
statisfied, then the second constraint (wait for 60 minutes) is 
processed, and is then satisfied. **(Note: The operator value of 
andSequence is not the same as and as for the latter, both operand 
Constraints must be satisfied, but could be processed at the same 
time.)** 

Which is wrong considering the definition of `odrl:delayPeriod` which 
itself imposes some sort of temporal dependency, hence doesn't rely on
 `odrl:andSequence` for doing so[2]: 

> The Action may be executed after the end of this period. **The 
starting time of the period is triggered by the satisfaction of 
another temporal constraint in a Constraint Relation.**

(ignoring imprecise wording for now)
