Dan: I think upgrading to MODS 3.6 is a good idea, but with respect to timing, it's probably a better fit as a component of or bug linked to bug 1638299 and targeted for 2.13/3.0. For the purpose of this bug, the patches I'll be submitting later today will remain limited in scope to just adding additional browse index definitions using the current stylesheets.
