This approach has its own problems (not flexible enough, rules are not very powerful compared to Mapnik and Osmarender) and I'm still looking for an alternative, but a complex XML schema is not on the top of the list. As for including rules within rules (if I understand your idea correctly), this is on my Kosmos "todo" list.
About the rendering priority: the order of the Kosmos rules on the wiki page defines (more or less) their priority - see http://wiki.openstreetmap.org/index.php/Kosmos_Layering . I don't know about Mapnik, but Osmarender's rules are prioritized by ordering, too.
