One thing I noticed:
> The application of the ‘mask’ or ‘mask-image’ properties to an element formatted with the CSS box model establishes a pseudo-stacking-context the same way that CSS ‘opacity’ does

Pretty sure is a real stacking context, not a pseudo-stacking context. Appendix E doesn't define "pseudo-stacking context" so we should probably just stop using this confusing term; the best description of what one is seems to be fantasai's recent email: <http://lists.w3.org/Archives/Public/www-style/2012Jul/0546.html>.
