Support Html, Head, Body?

[rvlzzr]

I don't think there is currently any easy way to set attributes such as lang, dir, or class differently per-route for the tags that only occur once per page (html, head, body), particularly with solid-start.

It would be convenient to be able to set such attributes using this package, even if it would expand its scope a bit.

I also really need this feature!
This isn't supported right now, so I'm in the process of writing a script myself.
