root scope: @this and @root

[Mouvedia]

hss file

@this {
//this should be matched by the root element
property: keyword;
}

@root {
//and this as well obviously
property: keyword;
}

Starting its hss file with @root { might become the norm since * { can be confusing in case you embed another xml document. Even if it's sanboxed, users could understandably think it's matching its siblings as well.
