Non-trivial software (TeX being the possible exception), in general,  
has bugs. Therefore, it is safe to assume that a conformance checker  
has at least one bug.

When the software is not a normative reference implementation, the  
bugs can be fixed without reissuing the spec when the spec prose and  
the software disagree.
