TTBOMK, you are correct.  Although there's a somewhat depricated address
scheme of user%host1 at host2 that has to be accomodated -somewhere- if one
truly wants full 822 compliance.  I haven't seen anyone use that in years,
though--like over a decade.

As I remember it, FQDNs can only contain [A-Z][a-z][0-9] and "-", as well
as their period delimiters.  Of course, they used to only be able to be 25
characters per segment, and I've seen that rule broken several times since
1998.  ICANN must have relaxed something at some point.
