== [css-syntax] "5.1 Parser Railroad Diagrams" ==
(migrated from mailing list)

**Raffaello Giulietti said:**

> In section "5.1 Parser Railroad Diagrams", railroads diagrams are 
> compared to (presumably finite) state-machines and regular expressions. 
> This is misleading: neither regular expressions nor finite 
> state-machines have the same expressive power as the railroad diagrams 
> used in section 5.1 (regular versus context-free languages).
> 
> Drop the comparision in section 5.1.
> 
> Note, though, that the analogous description in section "4.1 Token 
> Railroad Diagrams" is correct in that particular situation (although not 
> valid in general).

> bring much anyway so I dropped it as you suggested.
