The negation pseudo-class and Specificity

.wrap p - 011

.wrap p+p - 012

.wrap p+p+p - 013

.wrap p+p+p+p - 014

.wrap p+p+p+p+p - 015

.wrap p+p+p+p+p+p - 016

.wrap p+p+p+p+p+p+p - 017

.wrap p+p+p+p+p+p+p+p - 018

.wrap p+p+p+p+p+p+p+p+p - 019

.wrap p+p+p+p+p+p+p+p+p+p - 020

Specificity of Selectors
Selector	Spec.	Filter	Gecko 1.7~1.9 and Opera 9.5	Filter	Safari 3 (beta)
.wrap p	011	p:not([xxxx])	011	p:not(div)	002
.wrap p+p+p+p+p+p+p+p+p+p	020	p+p+p+p+p+p+p+p+p+p:not([xxxx])	020	p+p+p+p+p+p+p+p+p+p:not(div)	011

Conclusion

This is a test on the specificity of selector with a negation pseudo-class. What can be concluded is that Safari 3 (beta) treats the negation :not(div) with a specificity of 010 instead of 001.
