Re: [xml-dev] Relax NG and Web Services (formerly Joining the church)

[MDaconta@aol.com]

Hi Bill,

Sorry for the terminology confusion.  I was using XSD (for XML
Schema Document -- same as the file extension).  

Same point applies ... I agree that RNG and tool support for it
are on the rise.  The original question was "why would anyone
use anything else?"  The short-term answer is that XML Schema is 
still the only game for web services until WSDL 1.2 is adopted
and implemented.  

That is my current take on the situation,
