Re: [xml-dev] XML Schema question

Again, you should look at trang. I've routinely used RELAX NG in (past)
consulting work for companies and toolsets that only support XSD,
including big software companies in Redmond... After I leave, some clients
continue to use the RNC->XSD workflow; some ignore it and work only from
XSD. Either way, I would get to use RNC (RELAX NG Compact syntax).
