PQ: the url scheme does not allow the RD bit to be set.
The draft says "A DNS URI designates a DNS resource record set ... by
domain name, type, class and server.". That is, it identifies a location
within the abstract domain name space, a location which may contain
an RRset.
this statement would only be an answer to my concern if there were no way
to direct the query to a particular server using the "hostport" syntax. if
we're going to give the URL syntax a way to designate a server other than
the one which is authoritatively responsible for the data, or a local caching
resolver (also called a "recursive nameserver"), then we need to be able to
set the RD bit. personally, i like your answer better, but to reach that
answer we would have to remove the "hostport" syntax from the proposal.
