That's it alright, plus the fact that where there is disagreement, the 
resolution of that disagreement is up to the W3C XML Schema Working
Group, not any individual.

What we envisage is that as the number of implementation columns
grows, the tests will start to divide into three sets:

 1) Ones with unanimous judgements from all implementations;
 2) Ones with one or two minority opinions;
 3) Ones with a significant number on both sides.

Category 3 tests will be obvious candidates for being referred to the
WG.  Category 2 tests are most likely just wakeup calls for the
implementors in the minority to get with the programme, and/or cases
where the implementor acknowledges a lack of coverage.
