In my use case, it's defined that an example.com policy is used (if it
exists) in the absence of a foo.bar.example.com policy.  The problem is I
don't know how far up the tree to make that second query.

So in my case I explicitly will believe the parent/grandparent/whatever
statement, but I don't know how far up to go, and I don't want to ask
everyone; I only want to ask at most two questions.
