div::before {
  content:url(missing-image.png);
}

First, here too, the CSS3 double-colon grammar is used.

Second, some browsers like Konqueror 4.5.3 will display a real missing
image icon in place of that missing-image.png and this is acceptable,
expectable according to CSS2.1:

"User agents may vary in how they handle invalid URIs or URIs that
designate unavailable or inapplicable resources."
4.3.4 URLs and URIs
http://www.w3.org/TR/CSS21/syndata.html#value-def-uri

So, I think that testcase is invalid and should be removed.

Addendum:

Argh... I clicked the submit button a few seconds too hastily.

"
The value is a URI that designates an external resource (such as an
image). If the user agent cannot display the resource it must either
leave it out as if it were not specified or display some indication that
the resource cannot be displayed.
"
12.2 The 'content' property
http://www.w3.org/TR/CSS21/generate.html#content

Fair enough: the missing image icon is an excellent "indication that the
resource cannot be displayed" ... but the
http://test.csswg.org/suites/css2.1/20101027/html4/before-after-images-001-ref.htm
does not show such possible alternate rendering as acceptable to pass
that testcase.
