Is the XML Schema Test Collection still alive

["Gregor" <gregor@mrboogieman.com>]

Hello,

I am currently writing a paper which includes testing the validation
features of parsers. 

Therefore I need to test these parser with a massive number of test case and
so I decided to use the XML Schema test collection provided here:

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

Unfortunately the contributions are a little bit incomplete on the meta data
side (Microsofts XML-File describing the tests is incomplete, at least in
the current downloadables) and the promised reorganisation seems not to have
been occureed or is still going on.

I am very grateful to anybody for helping me with the following questions:

1. Is the schema test collection (especially the microsoft test case) still
usable e.g. uptodate with XML Schema 1.0se and generally thought to be
correct? Is there some work in progress regarding the upcoming XML Schema
1.1 rec?

2. Can I get the required meta data somewhere else?

3. An Implementation problem:
What parser set up did the original contributors use to test Xerces? (I get
Xerces2 (Java Parser 2.6.2) to validate the Schema4Schema against its dtds
but I run into problems trying to validate a Schema against the
Schema4Schema or is there some easyer way to tell a valid XML Schema from an
invalid one?

(@Admin: I know this is a Java question, but the XML Schema Test Collection
does validation of XML Schemas all the time so it at least partially and
very badly argumented fits here, maybe:)

Many Thanks and Kind Regards,

Gregor
