Whois++ (and in general all RFC822 derived formats) are basically flat.
There was an attempt to define a recursive data model (I think Dave
Crocker was the author), but it was not a pretty sight. SEXPR notation is
better, but displeases non lisp-hackers. The two can be combined,
e.g. a PICS instance in an HTTP header.
BTW, some parts of the example you used looked wierd - some strings were
in quotes, others weren't. If you do go for a sexpr solution it might be
better if you use something directly (read)able.
