Re: [precis] local case mapping

[Takahiro Nemoto <[e-mail]>]

Yoneya-san and I submitted new version of precis mappings document. 
We reflected comments from this ML in this version.
Please read and give your comments/suggestions whether this version 
is an accurate reflection of the comments.
BTW, Final sigma is too Unicode-y, so there is not final sigma in this document.

Regards,

Nemo
