RE: [w3c/dnt] Add more meta data in the Tracking Status Resource (#22)

I just worked on the draft TPE in github (to fix the site-wide indication bug)  and see that the remove* and confirm* calls now have their own PropertyBag dictionary (they used to derive from a template).

There is now no way to specify which storeSiteSpecific* call you want to cancel. A remove* would have to apply to all exceptions for that domain. The confirm call still has an  arrayOfDomainStrings in its dictionary so you could differentiate between exceptions with different sets of domains, but not in the remove* call. Also If you wanted to specify a different purpose in the "explanationString", you cannot cancel or confirm a specific purpose.

Editorial: there is a sentence about arrayOfDomainStrings in the confirmSiteSpecific call that refers to storing an exception  so makes no sense here, it should be removed.

I am not sure what you mean.  A site can make several different, additive, calls with different explanation strings (and one assumes different targets).
