Hi Nick,

I would like to coin the term inheritance instead of transitivity. I 
believe an object oriented approach to exceptions, like object oriented 
programming, is worth exploring. The relation between exceptions gives 
rise to hierarchy.

For example, maybe a large site could more easily specify the ad networks or exchanges it works with in requesting an exception (such that those domains receive a DNT:0 opt-in signal) and then all further re-directs would also be excepted, because the further third-parties aren't using the data for any additional purposes (via some version of our Outsourcing exception, and perhaps fitting an EU "data processor" definition).

Browsers could, for example, send DNT:0 to all resources that are re-directed from a request that was initiated with DNT:0, but that sounds both annoying to implement (for browser plug-ins, for example) and sometimes specifically not the intent of an exception (URL re-direction services, maybe).
