Yes, but that follows a very different spec from the one
given by the original poster, where the first rule was, as
above quoted, 'first character is numeric or "-"'.
Getting the specs 'right' for a fuzzily defined domain is
challenging, I was just trying to help implement the
specs the poster thought were right:-).
