I think a pseudo-element makes more sense as it represents an
element/box not accessible within the tree, whereas a pseudo-class
represents an element/box with an internal flag set accessible within
the tree.

Potentially we could have a new kind of selector representing an
actual element not accessible within the tree, but browser vendors by
and large have decided to use pseudo-elements, e.g.
::-webkit-slider-thumb.
