It can be a truth *compatible with* the model, if that's what you mean,
but it can't be a truth *of* the model if {lo pavyseljirna} has no referent
in the domain of discourse of the model. We can easily add the referent
of {lo pavyseljirna} to the domain, and the sentence {la djan djica
lo pavyseljirna} to the theory of the model, thus expanding our model,
and the new model would be consistent with the original one. But the
new model is not a model containing only John and elephants in its
domain of discourse, the new model contains unicorns too.

They are uninterpretable in that model. The usual move will be to change
the model (incorporating unicorns to its domain of discourse) so that the
sentence becomes interpretable.

That would seem to work as the analysis of "... wants that ...", as well
as any other propositional attitude. In this case the model will have a
domain of discourse which includes a person and a proposition.

If you are happy interpreting that sentence as involving hidden
propositions, that might work. I prefer an analysis that does not
make use of hidden things. For me all that the interpretation of
{la djan djica lo pavyseljirna} requires is a domain of discourse
with (at least) two members, John and unicorns. The sentence
can then be added as a true sentence of the model. It does not
entail that {lo pavyseljirna cu zasti} must also be a true sentence
of the model, but then why should it? I do not accept that
{ro da zasti} has to be a true sentence of every model.
