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] ")"
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.
