Shorten config.boot?

Is it possible to shorten the code with, for example, semi-colons? Or is there a syntax description?

from:

     rule 1 {
            action accept
            state {
                established enable
                related enable
            }
        }
        rule 2 {
            action drop
            state {
                invalid enable
            }
        }

to something like:

rule 1 { action accept; state { established enable; related enable } }
rule 2 { action drop  ; state { invalid enable } }
