One of the problems with the W3C test suites is that there's constant
pressure to remove from them any tests where the result is to any degree
implementation-defined or -dependent. For XML that might mean no tests for
encodings other than those which a parser is obliged to accept. In practice
that means a real parser will have large areas that the W3C test suite
doesn't cover.
