I think not not, any non-numeric value for tracktype would give a different
result than your table.

I think inventing such an operator would be a bad idea. It would be much easier
to have a genenral negation i.e.

!(expression)

But in general you can rework any boolean expression by exchanging the
operators, so that you coul go without a simple negation.
