First, a little bit of refactoring to make it cleaner to do unit test for each section. Then add some global error values. Throw in a helper function or two. Dust off the edges of the CompilerCallbacks object. Duct tape together validation of the normalization attribute. And ... eventually we get a nice clean-like unit test for the meta compiler, with three pretty little fixtures and as-neat-as-you-like-it assertions.
