The result is that {du'u} and {ka} are used in at least three different ways each (though I think there were four parties in the discussion) and, if you don't know the party of your interlocutor, you can get a wrong reading occasionally. By and large, though, if you see a {ce'u} in either context, it is a property being talked about. If you see no {ce'u} in a {du'u} clause, it is likely not to be a property, with a small but significant margin of error. {ka} is always some property of something, but which property and of what is not always clear, since {ce'u}s appear and disappear in the same context with amazing dexterity. So, for use, whatever you do, put in all your {ce'u}s. << A property abstraction is not the same as a predication abstraction. (an indication of this seems to be that a useful x2 place has be given to du'u and not to ka). And on the other hand I see no reference in the book for the use of ce'u with du'u. >> CLL is very quiet about {ce'u}, talking about it only in terms of {ka}, but also talking about {ka} without {ce'u} or any place for it. The use with {du'u} -- and eventually with any abstraction --, while allowed for in CLL, was developed from the post-book discussion that took off from the understanding of {ce'u} as a lambda'd variable in the lambda calculus (the one about abstractions, not the one about probabilities). {ce'u} doesn't work well in that role if you have occasions to want to bind two places the same way -- and pretty scary if you want to do that twice: \x\yFxyyx, is just hard to say in Lojban, though it can be done. That a property abstraction is not the same as a propositonal function is a contentious claim, though, amazingly, not one that was raised in the earlier discussion (I think). [I don't have reference numbers for the discussion but it seems to have stretch from August last year to April this, with a couple score of entries] The second place on {du'u} seems to have a certain use in mind, which is not this one, but is compatible with it (but almost never used, for obvious reasons).
