The client app probably wont do any proactive recovery, but when the user
initiates another query, it would try th UTF8 again, and fallback only if
the request fails again.  In the meantime, the cache server will have ready
the ACE respond already.  The cache resolver still performs its usual job,
not the client app.  The client app is only responsible for the fallback
mechanism.

The reason really for this proposal is to make sure that DNSSEC works within
the architecture.  If the resolver does any conversion, DNSSEC would have to
be changed.  But if the client falls back, the origination of the request as
well as the authoritative response is not changed throughout the resolution
path.
