Wouldn't it be useful also to define the behavior of `::before` and
`::after` for void and (especially) replaced elements more
specifically, with regard to the current behavior of the browsers?
E.g., all browsers currently support these pseudo-elements for `hr`
(and `hr::before { content: "\2727\2003\2003\2727\2003\2003\2727"; }`
is widely used in the new design of W3C specs themselves), although
this element [is defined as
void](https://www.w3.org/TR/html52/syntax.html#void-elements) in HTML.
Also, almost all browsers don't apply them to regular `img` elements,
but do apply for broken `img`s
(https://bitsofco.de/styling-broken-images/). Since the difference
between regular and broken differ in their browser Shadow DOM
structure ([at least in Blink
browsers](http://css-live.ru/Primer/pseudos/chrome-img-shadow-dom.png)),
maybe the behavior of pseudo elements also could be described in
Shadow DOM terms?
