[cddlm] CDL test files

I am seeking as many possible CDL test files to put into the set of test files I'm building up on sourceforge. Categories wanted -files that test the XSD matches what we expect. -files that are valid syntax, but invalid semantics - references that dont resolve - duplicate names - any other error documents -files that are valid. Particular those with early/late references, and what they should resolve to. I have all the examples of the CDL spec pasted in, but I want more examples to test references and expressions. What test files are the other implementors using? -steve
