[xsd-users] Re: [xsstl-users] Failed to use http://www.w3.org/2001/XMLSchema.xsd with the xds tool

[Boris Kolpackov]

Hi David,

First off, this a wrong mailing list ;-). xsstl-users is for XSSTL -
XML Schema Standard Type Library. You probably want to use xsd-users
for XSD (I've CC'ed xsd-users to this reply).

This sort of question pops up periodically on the xmlschema-dev
mailing list. The thing is XMLSchema.xsd is not really a valid
XML Schema definition and as such is pretty useless. W3C people
say it is not normative and is just for illustration.

If you want to play with some real-world schemas, I suggest you
take a look at the "Supported Standards and Schemas" page:

http://codesynthesis.com/projects/xsd/extras/supported-schemas.xhtml

It lists quite a few schemas from various industries.
