But not always at the end, which is why there's a problem. RFC1123, in my
opinion, contains a remark that ought to indicate to people that the
trailing dot convention isn't even universal for determining whether a name
is really fully-qualified. (See section 6.1.4.3. That RFC is also, of
course, how we got 3com.net as a legal name, for prior to 1123 "3com"
wasn't a valid label anywhere.)
