IMHO, the above representation is more intuitive than the representations
proposed by Alan and I and corresponds, in my mind, to the "closest"
representation to the negative assertion 'Sarkozy is not the President of the
USA"

Of course all these are logically equivalent representations, but they have
different connotations to the non-logically oriented subject matter
expert/ontology engineer.

This is precisely, why the syntactic sugar is a very good value add.
