RE: AltovaXML bugs? (and other engines)
The W3C test suites for XQuery and XML Schema are driven by a catalog of test cases: the syntax and semantics of the catalog are standardized, and there is a published set of tests and expected results. But there is no standard test driver; it's up to each implementor (or other user of the test suite) to write their own. The XQuery test suite also defines a standard format for reporting results. The W3C XSLT test suite is exactly the same, except that neither the catalog format nor the test cases are published outside W3C. The "framework" is thus essentially the catalog format. I don't think there would be any problem in publishing the catalog format (syntax and semantics) used by the W3C XSLT test suite, it's only the actual tests that are problematic.
