Language injection in HTML

Hi,

I'm trying to setup a language injection for Sass/SCSS in a HTML file but cannot get my head round how to do this. So, e.g. I have this code:

<style lang="scss">
    $font-stack: Helvetica, sans-serif;
    $primary-color: #333;

    body {
        font: 100% $font-stack;
        color: $primary-color;
    }
</style>

The help for language injections (unhelpfully..) only explains the list but not actually how to set up an injection up. I tried changing the existing "xml:style" and "xml:*/@style" settings to "Sass" or "SCSS" but that didn't change anything.

Although I'm not even sure if this is the right way forward? All I want is that SCCS code is properly syntax highlighted when included in HTML files.

Any help appreciated.

Thanks

Kai
