Re: [ubl] RNG schemas for UBL

[Hiroshi Naito <naitoh@is.oit.ac.jp>]

Hi, Jon and all Members 

Thank you for having interest in our report about Relax NG schema 
for UBL.

We are continuing to study how to translate WSD UBL schema to 
Relax NG and to develop translating programs with perl and XSLT. 

First beta vertion of whole UBL schema which are described with
Relax NG will post UBL ML until last year. Also we will report 
the problem periodically to the public ubl-dev list.

Thanks

Naito
