Basically, some (but not all) EPUB reading system implementors within  
the EPUB working group raised objections against the CSS pseudo-class  
solution, on the basis that they wouldn't be able to easily implement  
support for it, as it would require modifying the browser engine  
(other regexp-based, content pre-processing "hacks" were deemed  
unsuitable too, by the way).

The EPUB3 specification process is public, so here are useful  
references related to this particular issue:
