How about another ABNF extension, e.g.
/=?
rule = a
rule /= b
ABNF (RFC 2234) already has that - see section 3.3 in that document. The
syntax is a little different from what you have above:
rule =/ b
The one thing that is missing from ABNF in my opinion is an operator to
specify a list of items that can appear in any order. Tagged arguments in
SIEVE is a good example of where that would be useful - also iCal (RFC
2445) where properties within components can occur in any order.
