Usually this kind of things is done the other way around. Open BNF with
restrictions in prose on what may be produced. Or if one wants to go the
long way by introducing "obsolete/old" BNF constructs for stuff which is
should not be produced but still accepted by parsers for legacy reasons.

Notes in prose should not require parsers to go outside the BNF.
