[XeTeX] Mixed Roman and Indian alphabets for Sanskrit (was: what is \setmainfont used for?)

[Dominik Wujastyk]

This discussion reminds me of a long-standing question in my mind.
 hyph-sa.tex contains hyphenation rules for Sanskrit in several different
scripts, including Latin script.

The Polyglossia file gloss-sanskrit.ldf contains codes for invoking many of
the scripts in which the Sanskrit language is written, such as Devanagari,
Gujarati, Malayalam and so on.  But there isn't a rule for saying, for
Sanskrit, [Script=Latin].

How would this be done?  I've been looking at commands like
\xpg at fontsetup@latin,
but it's quite hard (for me) to see what's going on.  (I should get the doc
file.)

Has someone already solved or addressed this, or am I wrong about it in
some way?

The idea would be to be able to say

\setmainfont{FreeSans}[Script=Latin]
\newfontfamily\sanskGujarati{Code2000}[Script=Gujarati]

etc.

Actually, the more I play with this, the less I understand what's going
on.  I thought I had Polyglossia nailed, but I don't.   Why doesn't
\sanskGujarati set my text in Gujarati script?
