Hello All,
 
Xetex allows the use of input maps such as xetex-itrans for taking input in ITRANS transliteration and converting to devanagari .

xetex-itrans package is at
   http://tug.ctan.org/tex-archive/macros/xetex/generic/itrans/
.  Information is at
   http://tug.ctan.org/pkg/xetex-itrans
 
I am planning to use context-m-iv for some Sanskrit documents.
 
Is it possible to use the input maps with Context m-iv ?
 
Thanks,
Shree Devi
