I suppose you're right. So now we're back where we were, because the
"possible
worlds" cmavo can't be a UI - it doesn't have enough grammatical structure
that
way.

It may have to be a xVV cmavo. (It feels icky to use xVV cmavo when there
are
empty cmavo like {bi'a} and {ci'a} at our disposal, but oh well.) If so, I
would suggest that it should be a tense.






Oh, the grammar is not all that bad.  We need, however, to decide what the
critter is to do.  As I have said, I think the "possible worlds" talk --
outside of technical logic -- is a pretty bad one, since it goes so far
toward reducing all speech acts to describing/asserting.  In that view,
though, making moves to other worlds would be rather like a tense, except
that the world would be described situationally only, never by displacement
(what would be the metric of displacement after all -- or even the
direction?)  I think that the UIs work rather better: they describe the
displacement and permit laying stress when that is useful (it's the change in
my economic status, not a change in me that is important in {mi ricfu da'i},
say).  Which of these words we will use ({da'i}, {va'o} in a different way,
probably some others) and how they correlate with various brivla (I think
{sruma} goes nicely with {da'i} despite the different sources), is going to
depend upon what we find when we really start looking at the various kinds of
acts that may be out there: telling a tale is different from doing a proof
and that from contingency plannig or speculation about character or... .  We
need to find out what our resources are as well (what words can reasonably
play a role here?)
As for your sentence, I think all you really needed to say was {ledo logji
cmavo poi roroi mapti zoi <if, then> na da'inai roroi mapti zoi <if, then>}  
"What you call the logical connective that always matches "if, then" does not
in fact always match "if, then":" the putative conditional doesn't work".  
Otherwise, I'd stick {se sruma} in.
