In the CSS2 spec, a || means "in any order", so the answer is that
there's no order imposed on the tokens in the property, and "solid red
12pt" is valid.

See http://www.w3.org/TR/CSS2/about.html#property-defs for details of
the syntax that's used to describe properties in the CSS2 spec.

Cheers,

Jeni
