Section 3.2.3 says:

ccontent        =   ctext / quoted-pair / comment

comment         =   "(" *([FWS] ccontent) [FWS] ")"

It should say:

ccontent        =   ctext / quoted-pair

comment         =   "(" *([FWS] ccontent) [FWS] ")"

Notes:

Trying to getting all possible originator formats a reader can get stuck into a circular dependency between "comment" and "ccontent" definitions.
Since "ccontent" is referenced in the "comment" definition only circular dependency should be cut there I suppose.
--VERIFIER NOTES--
The ABNF for comment is correct in 5322. It is intended to be recursive, allowing for nested comments.
