    Couldn't you make another description for the operator, e.g.

    op ::= ','|'=>'

    and rewrite that as

    between_value ::= 'BETWEEN' '[' value op value ']'
                    |           '[' value op value ']'


    Or if you were using EBNF,

    between_value ::= ['BETWEEN'] '[' value op value ']'
