Ummmm.... Perhaps I should mention that the way Registrar is set up is almost
a one-for-one match with IAFA templates. What this means is that there is a
template for each URN, and each template contains a list of URL records, as
well as mucho other meta information. The only reason I wrote registrar to
begin with is that whois++ is, (as far as I am aware), currently vapourware,
and I felt it was really important for people to actually see something which
approached the problem.
