Can I claim 100% conformance to the Recommendation if my implementation passes all the tests in the Test Suite?
No. There are several reasons for this. • The goal of the test suite is to cover as many aspects of the W3C XML Schema Recommendation as possible. The TS cannot provide 100% coverage of the Recommendation – the methodology to do so with a specification as large and complex as W3C XML Schema does not yet exist. • Given that the TS is comprehensive, not complete, it is not possible to claim conformance with the Recommendation itself, since there is no guarantee that all aspects have been thorougly tested. Conformance can only be claimed with the TS itself. • The TS can tell you that your implementation does not support W3C XML Schema, by failing to pass a test, but it cannot tell you that it does, even when passing all tests. However, the XML Schema TS is a powerful resource for developers wishing to verify a processor’s support for W3C XML Schema features which are covered by the TS.
