Unit tests messed up on 0.9 branch

[Alan Gates]

When I run test-commit on the 0.9 branch I get three tests failing:   
TestTypeCheckingValidatorNoSchema, TestTypeChecking, and  
TestSchemaParser.  All three complain that the test class is not  
found.  It appears the test classes have been moved but that the  
commit-tests file hasn't been updated.  Is this a known issue?  Is  
someone working on this?
