/*!
The representation of CSS property values

Enums are named after the property. Variants have the same name + the
name of the value used in the spec. This leads to some verbose names,
e.g.:

The property 'background-color' and the specified value called '<color>'
in the spec lead to the variant CSSBackgroundColorColor(Color).

At least it's consistent though.
