nice and crisp.

I can really start to imagine how discovery and trust marks can be used to scale trust. Although there is some additional issues around the overarching trust framework (whatever that is, I am assuming law). For example assessing trust marks so that they are appropriate for the purpose and also for application in the framework, with a robust method for assessing and asserting integrity of trust marks.  In this context then I think it would be clear how the trust marks fit with VOT.  Its the gap between these elements I suspect that needs to be further articulated and understood.

nicely thought provoking   ..

I think that the vectors only make sense in the context of some kind of trust framework setup, but that sometimes those policies will be hard-coded at configuration time and won’t need to be dynamically bound or discovered. That said, I think the real value of this is going to be cross-domain where an RP could subscribe to (and understand) multiple trust marks and be able to validate them at runtime. Still, that piece might be separable enough, and perhaps substantive enough, to be its own draft.
