Subject: Re: [ubl-dev] The announcement of RELAX NG Schema library for UBL 1.0Beta
Kon'nichi-wa Naito-san: I would add one more requirement to your list if possible. I would think that Relax-NG must also be capable of expressing the same level of constraints as W3C Schema (for instance - expressing multiplicity and datatype constraints). This is a very large task you are undertaking. Thank you for your efforts.
