Re: CSS3-selectors: Pseudo Elements only once or multiple times per selector?

The issue was the sentence : "When the :first-letter and :first-line
pseudo-elements are combined with :before and :after". It was giving
the impression that p::first-letter::before was allowed. That's not the
case, only one pseudo-element is allowed per selector, at the end
of the last sequence of simple selectors.
