Re: [xml-dev] XML Schema question

Maybe it will catch on so much in Redmond that the guys responsible for their
servers, platforms and database get hooked on it too :-) Last time I looked
there didn't seem to be anything serious that would run RNC or RNG in .NET
though :-(  I probably won't get far in my environment running
anything in a JVM.
RNG guys are certainly persistent though. And thanks for those links to Trang.
