The CSS Working Group has resolved not to add 'background-opacity'
to the CSS3 Backgrounds and Borders module. We are considering this
functionality for the future (e.g. see discussion about filters from 
<http://lists.w3.org/Archives/Public/www-style/2009Nov/0252.html>)
but it likely will not be expressed as a 'background-opacity' property.

Please let me know if this is acceptable. :)
