[tex-live] numerals in xelatex

[Zdenek Wagner]

Hello,
I am trying to extend the Hindi module for babel so that it works in
XeLaTeX. The only problem is that automatically generated numbers as
\number\day in the definition of \today or \thepage (essentially
\arabic{page}) are displayed as Arabic numbers, not Devanagari. Should
I prepare a mapping and use something like
\addfeature{map=devanagari-numerals}, or is there some better way?
Other Indic scripts will have the same problem, so I would prefer some
universal solution.
