Hum, and if I want to apply the 7pt, I need to define another rule for the 
::inside

So, I need this :

myElem { // Defined globaly
    font-size: 7pt; line-height: 7pt
}

myElem#specialItem::before { // Defined localy
    content: '\A\A';
    font-size: inherit; line-height: inherit;
}

myElem#specialItem::inside {  // Defined locally
    font-size: 7pt; line-height: 7pt
}

And what happens if someone decide to change the 7pt to 8pt later ? Does 
this person
need to look at every local page if there's no rule that was used to 'hack' 
the ::inside problem ?

x::outside don't herit of x's properties, because x::outside is the 
ancestror of x.
It's x that inherits from x::outside. Wrong ?

Why should this be easier to implement ?
