[css3-background] background-size in 'background'

Hi,
In the  the css3-background editor's copy [1], the background-size 
property in 'background' is written '(10em)', which is not a valid 
production, and not decribed anywhere.
Please change this to 'bgsize(10em)' or 'size(10em)' (or anything you 
think is better :) )
Thanks,
