Michael,
To unconditionally undefined a class (which is what -N does) you could define
it as an expression that always evaluates to false:
classes:
"class_to_undefine" not => "any";
To negate an existing class (not necessarily undefining it), I don't think you
can do it on top of the same class, but you can certainly define a new class
with the negated value:
classes:
"negated_class" not => "original_class";
or
classes:
"negated_class" expression => "!original_class";
