Perhaps it would be a good idea to make a distinction between
URN lookups and searches involving URNs ? The whois++ handle
mechanism, or something like it (another char instead of "!" ?)
could be used for bare bones URN lookups (return the full URC
associated with this URN), and the

template=URN;URN=<rhubarb>

syntax used for everything else. This would make it a bit
easier for server authors to optimise for URN lookups, and URN
servers could be deployed which only needed to understand

!<rhubarb>

e.g.

% 220-whois++ server cuppat, LUT mini_whois++ 1.0
% 220-only understands handle and urn lookups!!
% 220 your mileage may vary
!urn:iana:rfc:822
% 200 command ok
