I have just checked in [1], into the trunk, support for a new CSS 3 pseudo-element [2]. A test case is available in the bug showing how to use that pseudo.
Please note that the pseudo is for the moment called :-moz-selection but should become ::selection once support for "::", in conformance with specification [3], is added to the trunk.
