DDEX messages make use of two-letter ISO territory codes. This allows a label to state that a Release may be used in, say the “DACH” countries:


It also allows to say that a deal is available everywhere but in the DACH countries:


The latter XML snipped has the semantic of "World-wide, less Germany, Austria, Switzerland". .

To avoid this pitfall, the label should limit its Deals to the territories it would want the DSP to make the Release available in.

DSP expanding its territorial reach

If a label sends a DSP, who operates in only one territory a Deal with


and the DSP subsequently choses to branch out its operation into a second territory, the Deal would allow the DSP to make the relevant Release available in both territories.
