IE supports "position", but it does not support "position: fixed".

Well, my grammar already specifies a syntax, although the prose doesn't
really explain. You can specify a bare property name or a property:value.
@supported [ opacity; position: fixed; ] { #myel { color: red; } }
so #myel would only be red if the UA supports the "opacity" property
*and* the "fixed" value for the "position" property.
