It is not completely valid. It is for {lo}, but not exactly for {le} and
{la}.

{le mlatu} is "each one of those I describe as a cat (in this context)",
not just one or more of them. For example, {mi viska le mlatu}
mens "I see each of the cats", and not "I see at least one of the cats".

Remember that {le mlatu} is by definition equivalent to
{ro le su'o mlatu}, and {lo mlatu} is by definition {su'o lo ro mlatu}.

That is what the book says, but I use {lei} in the same way as {le},
i.e. for the whole mass, and not for "a part or the whole". For example,
I would not say {lei cukta cu grake li ciki'o} = "the books weigh 3 kg" if
only part of the books weighed that. To me that means that the whole
mass of books weighs 3 kg.

Yes, although my recomendation is never to use them. If these are
supposed to be mathematical sets, they don't have much use in ordinary
language. Even in places where they are apparently needed, it is not
clear to me why they would be better than masses. For example:

        mi cuxna lo creka lei nenri be le dacru
        I choose a shirt from among the ones inside the drawer.

        mi cuxna lo creka le'i nenri be le dacru
        I choose a shirt from the set of ones inside the drawer.

Is the second expression in any way clearer than the first?
Does it add anything? I don't see the point of having the set articles.

You're absolutely right. {lei mlatu} is a mass of those I describe as cats,
not a mass that I describe as a cat.
