Quoting that document (an "internet draft" of the sort which anyone
can submit any time), we find it is not supposed to be quoted :-)
Operational Guidelines for "local" zones in the DNS

Status of this Memo
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference material
or to cite them other than as ``work in progress.''
I haven't really caught up over the last 18 months with what has
happened in the big IETF debates about mDNS (so-called "Apple") vs
LLMNR (Link-local Multicast Name Resolution - so called "Microsoft").
But I haven't heard that there is anything on the road to
RFC 4795 was published http://tools.ietf.org/html/rfc4795
Link-Local Multicast Name Resolution (LLMNR)
but that is just an "Informational" RFC, and just about anyone who is
persistent enough can get one of those published.
Security issues have been identified with both of them,
since they let systems mess with names that look like
official dns names.
I find a lot of appeal to finding a good standard for simplified
configuration, like zeroconf. But I think that it is a difficult
thing to get right :-(
