Re: [xml-dev] XML Schema question

[Evan Lenz <Evan.Lenz@marklogic.com>]

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).
