These are filtered out of the model. + + So there is some ambiguity about intervals that end at time zero. However, the + first statement seems more authorative ("the strict definition") and the + second statement does not explicitly say that intervals that end at t=0 are + not filtered. Furthermore, the pseudocode is in agreement with the first + statement so we conclude that if an interval finishes at time zero it is not + an acceptable interval and is filtered out. + + The following animation sets up such an interval, that, based on its + repeatCount has an active duration of 1s, producing an interval of (-1s, 0s). + Therefore this interval should be filtered out and no animation effect should + be produced.
