No, you have not. I've read your documents, and I'm not convinced. 
Perhaps you have a good and valid point, but if so you haven't made 
it convincingly yet. Perhaps you can make your argument more 
persuasively than you have to date.

This is the least convincing part of your argument. XHTML 2.0 asks 
page authors to do exactly that. It is backwards incompatible with 
HTML. Why you think linking must be compatible when frames, images, 
and more aren't, I just don't understand. If backwards compatibility 
were an explicit goal of XHTML 2, then I could see your point.

I am not convinced it is necessary to "use a bunch of arcane attributes
on every linking element". So far, it still seems to me to be 
possible to stick with xlink:href and element/GI defined semantics.

If you were able to demonstrate a need for these requirements, then 
this point would be relevant. But so far, I am unconvinced that HTML 
needs multiple link attributes on a single start-tag, or that it 
needs them to be named something other than what they are named in
