I think that explicit/explicit allows to determine the number of 
controllers. 

For processors You would use 
"same-party": [
    "example.com",
    "example_vids.net",
    "example_stats.com"
  ]
to indicate them. Because from a DNT point of view, a controller and her 
processors are one bucket-entity. Here DNT may serve as a consent mechanism 
also for the first party. (An optional beneficial use, an enabler in EU, not 
DNT for first parties in the US)

This is the case I have in mind. To monetize the content, the site has P 1-4 
but at least wants to have P1 and P2 to receive DNT;0

The question for me is: 
1/ Self determination means I can send DNT;0 to P1-3 and DNT;1 to P4. The 
normal shortcut would be "*" meaning P1-4
2/ "*" alone is not a list of controllers. The consent would be for an 
undefined object that changes dynamically over time. Is that missing 
determination of controllers at communication time a problem for the 
consent?

This is the goal if we want to make DNT in any way useful for the EU market.
