Upcoming change to ::pseudo-elements / :pseudo-classes syntax

It looks like we have mistreated CSS syntax regarding using pseudo-elements and pseudo-classes when they are specified in the same selector. The order does matter and it should be different.

This is wrong:

<style type="text/ample+css"> @namespace xul "http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"; xul|textbox::value:focus { color: red; } </style>

While this is correct:

<style type="text/ample+css"> @namespace xul "http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"; xul|textbox:focus::value { color: red; } </style>

Expect the order to be changed in the next version of Ample SDK.
