[Opendnssec-develop] Running with no policies

Hello,

Agreed, that's the sort of exception that usually leads to weirdly structured
programs.  Agreed, that a system without policies has no need for data.
Agreed, treating zero-cases gently as a normal part of operations instead of
as an exception is a good idea.  But I cannot judge if this is practical, which
makes me humble instead of pushy towards this somewhat theoretical form of
beauty.  In short: whatever you think makes sense!

Indeed, and syntax already takes care of that: a zone can only be defined with
a reference to a policy that is known to the system.

Simpler is better, certainly if it makes the concepts more elegant, that is
less exception-ridden :-D

Good thinking, Sion!
