[dsdl-discuss] Re: What is the best way to simulate

Rick

I'm confused (not an unusual situation I know!). Why is SimpleLiteral based
on anyType rather than being a simple string? Are you expecting someone to
want to extend these definitions by specifying a specific type, such as
xsd:date for the date element? What other DC elements would need typing?

Just as a little progress report on my XSD to RNG converter, here is the
MS Dublin core schema in its XSD version and in the RELAX NG version (I
use Trang to convert it from RNG to RNC.)

Cheers
