i regret not saving your original example. can you show me a case where
the first time a label is seen, it's not from an authority? in my own
situation, gw.home.vix.com has an empty non-terminal "home" which will
be first introduced to a recursive server by the vix.com authority. if i
wanted it to be "GW.Home.VIX.com" then i'd have to set the case
correctly in the vix.com authority, and ask verisign to make my
delegation in com all-upper-case. this is more complex than my
above-quoted example, but still leaves the domain owner in ultimate control.
