Yep, of course that was the paragraph I was reading too.

It is kinda weird that, with all the many things that emacs can do, it 
can't take the info from doc-view (which obviously understands all the 
pieces of a pdf-- down to its bits-- and how they all go together to 
make a document) and edit it... it's pretty much implausible to believe 
emacs *can't* do that.  But then, I've always thought reality was 
completely implausible.  :^/
