Nominalized possessive phrases

We can say ka pasúo ka kunu "the dog's food," so logically ka ka kunu must be"the dog's one, the dog's," etc. It's kind of weird because essentially ka ka ends up being a compound particle introducing definite possessives, but you can't argue with the sense of it.

Ka ni i iso i taha ka se "mine is bigger than yours." I suppose there could be some minimal word requirements that would give us ka nii, ka sei, etc...maybe. But anyway you get the point.

Note from 2016 as I'm posting this thing I just unearthed: just because ka ka kunu is logical and has to be admissible, that doesn't mean it's the best way to express this in Koa or that there couldn't be other ways. Using asi as a potential candidate, we could do something like ka asi ka kunu "the dog's (one/thing)," ka asi ni i iso i taha ka asi se "my one/thing is bigger than your one/thing" if needed. Actually I don't dislike my original renderings of these at all, but I can see how the embedding could continue ad absurdum and I just wanted to insert some sanity...
