Pseudo-elements are a concept from CSS, where they are currently defined
and are finite. Maybe in a future version of CSS we could have
parameterised pseudos, but it seems simpler for now to have the limited
subset currently available.
In either case, this would be an issue for CSS, not XBL. XBL is merely
using what CSS makes available.

In CSS3 'content' applies to everything.
