I have realized that this is your claim, but I still don't
see that it has to be identificatory.

No, this is intended as a question about the type of cat.

It doesn't assume this. Specificity is not the same as
identifiability, at least not for the hearer.

That's right. The point of this dialogue was to show that {le
mo broda} needn't be asking a which-question.

"I saw a certain 'cat' in the park."

"a certain 'what?-type cat'?"

"a certain 'white cat'"

Okay, I'll discuss this {le ki'a} suggestion now. Here are
two problems with it.

First:

   A: le nanmu ............ le nanmu
   B: le ki'a nanmu

B is saying that {le} provokes confusion. What sort of 
confusion? Presumably, about what the referent is.
HOWEVER, it could simply be confusion about whether
the two {le nanmu} sumti share the same referent. In
this case, all B is saying "is this le ba'e, or not?",
and B is not saying "give me sufficient information
to identify the referent".

Second:

I may be wrong, but I don't think {le ki'a kau} can be 
assumed to work as an indirect question. Yet we do want
to be able to say "He told me which book he was reading".
A fully satisfactory solution for which-questions will
generalize to indirect question contexts.

John has answered this:

   % "A certain" in English is a way of making +specific 
   % -definite sumti: I know what cat is meant (+specific), but
   % you don't (-definite).  In Lojban "le bi'unai mlatu".

Maybe it would be more helpful to think of things this way:

A; le broda goi ko'a cu brode
B: ko'a mo

Whatever question B is trying to ask, it remains the case that
ko'a has a guaranteed referent, even if B cannot identify ko'a.

I contend that B could equally well have said "le broda cu mo",
where "le broda" would have a referent guaranteed either (a)
by B being able to identify it, or (b) by it being coreferential
with the {le broda} in A's utterance.

This is a hypothetical problem for {ma du le mlatu} but not
{ri du ma}. But anyway, {ma du le mlatu} is asking about
a specific cat, namely the one that A was talking about.

Actually, no. I'm wrong and I should go to bed now. 
If B wants to say or talk about "the cat(s) A was referring
to" then this is {ro lo mlatu poi fe[?] ke'a tavla fa do}
or {ro lo mlatu poi di'e valsi ke'a}.

If B instead uses {le mlatu}, then this could refer to the same
cat as A was talking about, even if B can identify it by no
unique property other than the property of being talked about
by A, but there is no guarantee of this coreference; A would
have to glork it from context.

{ri du ma} works okay though.

Hopefully I'll be thinking more clearly when I've caught up
on sleep deficit.
