Unclear mapping between "Area of Service: Region specification" and "Area of Service"

How is the mapping between "Area of Service: Region specification" and "Area of Service" supposed to work?
"Area of Service" contains a list of ISO 3166-1 Alpha-2 country codes.

Let's assume as example that "Area of Service" has the values ["ES","FR","DE"]

"Area of Service: Region specification" specifies a list of regions for each of the countries listed in "Area of Service".

For the example above, we might need to specify up to 3 lists in "Area of Service: Region specification": one for ES, one for FR, one for DE, with example values: [["ES",1,2,3],["FR",0],["DE,2,4,5,7]].

How these lists are supposed to be represented according to the tmf633 service specification provided in gst.json , where "Area of Service: Region specification" is defined as a set of integers?

Shouldn't "Area of Service: Region specification" be defined as a set of sets of integers?

Can you please provide an example?

Probably each region of the world might have its own ID (global in the system). Then this could be addressed with the help of UI. @kostistr
