DDEX messages are explicit in all communicartins. For instance a DSP may only offer a release to its users, if an explicit Deal is provided.
There is, one exception to this rule: The communication of territorial variations of Release descriptions. For these, the rules are
- The first …ByTerritory composite (in a specific Release, Resource or Work composite) communicates the default values that apply to all territories; and
- All subsequent …ByTerritory composites (in the same Release, Resource or Work composite) only provide those elements that are technically mandatory or differ from the default.
