I'm not talking about the formal specification, but the implicit specification of what people have been using for decades. That only has 5 keywords and a couple control characters. The formal spec is based on that informal spec, which again, isn't that complicated.

To be more direct: what are all of these assumptions you assume google's parser is mishandling?
