Does Conformance mean I can state a 100% conformance with the XML Specification if my implementation passes the XML TS?
No. There are several reasons for this. • The goal of the test suite is to cover most aspects of the XML specification, although It seems impossible, or or at least very hard to cover every conceivable aspect. • Given that the XML TS is comprehensive, not complete, it is not possible to claim conformance with the specification itself, since there is no guarantee that all facets have been thorougly tested. Instead, conformance can only be claimed with the XML TS itself. • The XML TS can tell you that your implementation does not support the XML specification, by failing to pass a test, but it cannot tell you that it does, even when passing all tests. However, we believe that the support given by the XML TS is substantial and helps implementors to significantly increase the support for XML in their implementations.
