From last May's MSDN Mag at:
"Once it is finalized by the W3C, the standard XML Schema Definition
Language (XSDL) will replace the current XDR syntax."
To my knowledge, MSFT came up with XDR as they needed something to work with
until XSDL got to a reasonable stage in its ratification program. They
stated specifically at TechEd last year, that XDR was an interim measure, so
not to invest too much effort in it.

Subject: Re: XDR
XDR is Microsoft's XML schema implementation, built into the MSXML parser.
A schema (if you didn't already know ;-), is similar to DTD's but goes
beyond the structure and content definition of a DTD and provides data
typing for element and attribute values, among other things.
The XDR technology competes with the W3C technology called XML Schema
(http://www.w3.org/XML/Schema). Because of its W3C backing, XML Schema will
garner widespread support, and already has to some extent, based on what
I've heard vendors are doing.
I'm not sure who else is supporting XDR, but there are surely some vendors
out there. I believe I've heard Microsoft will support XML Schema in the
future (anybody have definitive news on this?). Microsoft does have a
converter that transforms an XSD to an XML Schema (see
