What I meant was that the above looks a lot like a repeat of what we
originally called styling, just without the box model fresnel:container
/ resource / etc. Style terms. Sorry for the lack of clarity.

The CSS selectors would be applied to XHTML derived from the
intermediate tree. The '.fresnel:' prefixes are a shorthand to indicate
that an XSLT author would have to use some agreed upon token for
resource / property / label / value to avoid collisions in class names,
but it wasn't intended to be a defined part of Fresnel in my mind.
