Trusted resolution

I still haven't gotten the ok to distribute the trusted resolution proposal,
but I also had an action item to provide alternative text for section 4.9 of
the requirements doc. How's this?

The XRI specification must ensure that the specified resolution mechanism(s)
can be extended to provide trusted resolution. Trusted resolution in this
context means the relying party (i.e. the party requesting resolution) can
trust that the result of resolution is correct as defined by the resource's
controlling identifier authority. Specification of the actual mechanism for
trusted resolution may be out of scope for this effort. Data confidentiality
and access control are explicitly outside the scope of this requirement.
