>     CSS authors don't want to know about constraints imposed by the
>     CSS tokenization, it should just work intuitively.

> For <An+B> (In the :nth-*() pseudos), what constraint specifically is 
> this referring to? The <An+B> grammar (which authors do not need to 
> know), is so complicated precisely to work around CSS tokenization and 
> relax whitespace constraints for authors.
