W3C XML Schema Test Collection

[Jonathan Robie <jonathan.robie@softwareag.com>]

Executive summary:

1. XML Schema test suites exist, and are being maintained by the W3C. This 
may be one of our best points of leverage.
2. The public is encouraged to add cases to the test suites
3. Some test results are available online for various products

Here are the details:

Recently, I suggested that we demand compatible XML Schema implementations. 
One of the ways we can do this is to leverage the W3C XML Schema Test 
Collection:

         http://www.w3.org/2001/05/xmlschema-test-collection.html

The general public is welcome to submit test cases for inclusion in these 
test suites. To contribute a test, fill out the following form:

         http://www.w3.org/2001/05/test-materials-license.html

Mail your test cases to:

         www-xml-schema-tests@w3.org

I was not able to find an archive for this. I will ask about this in the 
XML Schema WG - I would have expected this list to be publicly archived.

Here are the test suite contributions as of 16 January 2002:

         http://www.w3.org/XML/2001/05/xmlschema-test-collection/results-master.html

Note that some test results are online, generally comparing either MSV or 
Xerces to XSV. For instance, here are the cases where Xerces, MSV, and XSV 
treat identity constraints differently:

         http://www.w3.org/XML/2001/05/xmlschema-test-collection/result-ms-identityConstraint.htm

Here are cases involving complex types - search for the string 
'restriction' if you don't believe the claims that derivation by 
restriction is not implemented consistently across XML Schema implementations:

         http://www.w3.org/XML/2001/05/xmlschema-test-collection/result-ms-identityConstraint.htm


Can the XML-Dev folks contribute a bunch of useful cases to these test suites?
Can we put pressure on our vendors to publish the results of these test 
suites for their products?
