TECHish: query on syntax of jai & fiho

[ucleaar <ucleaar@ucl.ac.uk>]

Does jai [convert modal to x1 of selbri] *follow* the modal tag, as
in "LE BAI jai SELBRI"?
Does fiho [convert selbri to modal] *precede* the selbri?
Do the non-x1 [including demoted x1] places disappear from the
fihoed selbri?

Thanks.
