This may make sense to some extent, but it's not totally clear that
all future additions to the Unicode list of scripts can be just added
to the list of input mode tags in XForms. It is certainly not the case
that the current list of scripts in Unicode is identical with the
(currently proposed, incl. below) list of tags in XForms.

Also, because there are changes in spelling, I think it's much
more useful for implementers and users to have a full list.
What I could immagine is that we add a sentence saying something
like "it is expected that future versions of this specification
will include tokens for scripts added to Unicode wherever that
makes sense".

Regards,    Martin.
