That is unfortunate, because it is probably substantially different
in SL-compatibility. The main differences in expressive power
between 3XS and 4XS is that 4XS allows you to quantify over pairs
(and other n-somes) of broda and over halves (and other fractions)
of broda. I will post another message giving the gist of 4XS.

You pinned them down to prototype & made a ruling that solved the
problem of uninheritable properties. ("The zoologist studies the lion"

Two extensional sets are identical if they have the same membership.
Two intensional sets are identical if they have the same defining
feature (the same membership criterion).

Okay, but I can't promise that we won't find differences between
"is water" and "is a portion of water".

It is cheating under the 'bit of substance' analysis.

Why not abbreviate thus:
pa lo su'eci'ino [spisa be piro loi ci'ipa] broda
instead of thus:
pa lo [su'eci'ino spisa be piro loi] ci'ipa broda
? That seems more SL-conformant.

We need to quantify over members of Mr Broda Pair. How do we do that?
{PA lu'i tu'o lo(i)}?
I haven't worked out how to quantify over subkinds of Mr Broda, either.

"by brivla", you mean? If you set aside your abbreviations, and use
tu'o only where it isn't an abbreviation, then {PA lo tu'o lo broda}
makes perfect sense.

4XS is compatible with lo broda remaining an individual, if loi broda
becomes a kind. Of course, then {loi} would not mean a jbomass.

That's not a logical confusion. It's a confusion about the meaning
of substance selbri ('substance' vs 'bit of substance').

I don't see a problem with {tu'o} for kind, though {PA lo tu'o}
should give us subkinds.
I have fought my way through only 2/3 of your two megapostings.
I think what I'll probably do next is see if I can apply your
proposal myself to 4XS.
I'm not sure how kludgesome yours really is. A lot of the verbosity
is due to conversions between types that in practise would be
left to glorking. I don't think we often want to convert between
su'omei and substance.
