Thanks.

I think it would have to define what counts as a profiled subset. May  
anyone define the profile? Does it have to be defined by a W3C spec?  
Does DOM Level 2 Core count as a profiled subset of DOM Level 3 Core?  
Does SVG uDOM (the core-related part) count? I think this criterion  
is still not testable as written.

Same comments as above.

Sounds good.

I am satisfied with the specific resolutions for these comments, but  
I think Appendix B is still problematic. It sounds like the only  
conformance requirements will be requirements to implement other  
specs (L3 Core, L3 Events, Window). Maybe that's ok to publish, but  
it doesn't sound all that useful to have a spec that is just a  
laundry list of other specs.
