<style scoped> is translated to <link rel="stylesheet" scoped> however there is no browser support for the latter

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open source of https://www.highdefinition.ch/test.html?ModPagespeed=off
2. open source of https://www.highdefinition.ch/test.html
3. look for "scoped", compare

What is the expected output? 
<style scoped="scoped">@import url('/styles/kendo.metroblack.min.css')</style>

What do you see instead?
<link rel="stylesheet" href="/styles/kendo.metroblack.min.css" scoped="scoped"/>

<link scoped> is currently not supported by any browsers. The 
<style>@import</style> workaround has to be used. This translation of mod 
pagespeed is not only useless, it breaks the page.

header)?
