All of my comments appear at the top of this message. 

I hadn't really noticed the issue that you pointed out regarding the fact that
guideline 11 mentions W3C technologies specifically but covers more than W3C
technologies.   I like your suggestion of changing the guideline to read 
something like "Support Open Specifications and Known Accessibility
Features."   But I still think the wording of  checkpoint 11.2, Support
appropriate W3C recommendations is confusing. Maybe I am just not in synch
W3C terminology.  Are there inappropriate W3C recommendations or are we saying
support those recommendations that apply to your user agent?  Maybe it should
just say Support W3C recommendations with no qualifier.  Are "W3C
recommendations" different from "W3C technologies"?
