17454	Support conditional syntax for interval	nlehuby	team	"We can now use interval:conditional (and a few other tags) to map the headway on public transport lines : https://wiki.openstreetmap.org/wiki/Proposed_features/Public_transport_schedules/Interval

But JOSM validators reports a bad syntax for the interval:conditional tag.

To reproduce, you can test for instance with this object : 
https://www.openstreetmap.org/relation/9348862
interval:conditional = 15 @ Mo-Fr 05:00-09:00,16:00-20:00; 60 @ Sa 05:00-10:00,20:00-22:00
