AdsML Standard -- Opening an Envelope

Edifra recommends the principle one ad order-one artwork. If an ad is to be published three times, there are three separate ad orders. In AdConnexion, this can be done with one ad order that has three publishing dates for one piece of artwork. In case of one order-multiple artwork, a communication problem may arise when, for example, a package of seven publication dates is ordered and the newspaper can only publish six of them.
