[1] For the RFC lawyers, not of any actual operational value: There
are some RFCs that specify some of this behaviour, I believe, in the
context of zone transfers rather than DNS queries but those RFCs
really just document the behaviour of that one authoritative server,
and most people consider them a mistake worth forgetting as far as
being a Standard with a capital S is concerned, rather than just
documentation of current practice with that one server.
Unfortunately, there seems to be a critical mass of people in the DNS
part of the IETF that believe otherwise, that the only problem with
wildcards is that there are servers that don't do exactly what BIND
does, and the solution is to fix them so they do.
