The Chomsky ex isn't nonsense -- it is merely surreal & doesn't cohere
very straightforwardly with out experience of the world.

I have no problem with the Formal Grammar or Official Parser passing
nonsense. But any truly well-formed sentence of Lojban must be meaningful,
however silly or surreal that meaning is. A true parser will recognize
which strings are and aren't meaningful. A parser that ignores meaning
is nonsense, in the sense that it produces nothing useful.
