It is.

CSS2.1 doesn't really clearly define the processing model of 'content' 
on ::before and ::after, but the informative examples in CSS 2.1, the 
fact that 'content' specifies a _list_ of things, and the desire for 
consistency has led to UA behavior being the following: the 'content' 
property specifies a list of things that become children of the ::before 
or ::after box.
