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). http://www.thaiopensource.com/relaxng/trang.html http://code.google.com/p/jing-trang/ Evan Lenz Software Developer, Community MarkLogic Corporation On 3/1/11 1:39 AM, "Stephen Green" <stephengreenubl@g...> wrote: >Many thanks Evan.
