This follows recent discussions about negation in PRD,
here called 'Nio' (Negation inflationary operator).
The FLD EBNF at
http://www.w3.org/2005/rules/wiki/FLD#EBNF_Grammar_for_the_Presentation_
Syntax_of_RIF-FLD
could be extended for 'Nio' and abstract
FORMULA ::= . . .
IRIMETA? 'Neg' FORMULA |
IRIMETA? 'Naf' FORMULA |
IRIMETA? 'Nio' FORMULA |
. . .
to
FORMULA ::= . . .
IRIMETA? NEGATOR FORMULA |
. . .
NEGATOR ::= 'Neg' | 'Naf' | 'Nio' | KBRDSTRING
paralleling similar abstractions we did for the
(binary) CONNECTIVEs and for the QUANTIFIERs.

PS: KBRDSTRING is FLD's handle for extensions.
