I taught an introductory class on MODx last night. There was a point where I needed the navigation generated through wayfinder to have specific classes. I was able to generate inner and outer name parameters without a problem, but got a little bogged down when I needed yet another class name on the <a> tag—probably confusing a couple of students while I figured out the issue.

My advice to anyone teaching a technical course is to never try to figure anything out on the fly. Always be prepared for every possible variation, question, and/or scenario before stepping foot into the classroom. It will prevent confusion and keep people from getting lost.
