[RC3] before-after-floated-001 relies on CSS3 double-colon grammar for pseudo-element

The following (CSS3 double colon grammar) ::before and ::after is not
CSS 2.1 compliant:

div::before {
  content:counter(ctr) url(support/square-outline-32x32.png) open-quote
"Before " attr(class);
  counter-increment:ctr;
}
div::after {
  content:counter(ctr) url(support/square-outline-32x32.png) "After "
attr(class) close-quote;
  counter-increment:ctr;
}

.beforeleft::before {
  float:left;
}
.beforeright::before {
  float:right;
}
.afterleft::after {
  float:left;
}
.afterright::after {
  float:right;
}
