The new constant is PAGE_COURSE_VIEW, and it's more streamlined with the new CSS-related ids for 1.5. There are great possibilities for the future here, so we 're getting ready. On the other hand, this has to be the ugliest hack I 've ever inflicted on any program (look at pagelib.php). Thankfully it will only stay for just a little while.
