As far as I see the current usefor draft (for lack of better
documentation), section 3.1.4 in
http://tools.ietf.org/html/draft-ietf-usefor-usefor-12 I'd say that's
sufficient if the exclusion catches all your binary groups, the
newsgroup name can be ALPHA, DIGIT, +, - or _, with . obviously as
component separator.
