(They have near-∞ passing conditions, not 1.) I think the idea was that the *reference* would have a negative reference. So you'd have an assertion: test == reference != not-reference where not-reference would be the same as reference except with the feature in question removed. For example: test: transform: rotate(45deg) reference: transform: matrix(...) not-reference: no transform -David -- 𝄞 L. David Baron http://dbaron.org/ 𝄂 𝄢 Mozilla http://www.mozilla.org/ 𝄂
