I did this by defining partial interfaces for each of Document, 
DocumentFragment and Element, rather than having a single NodeSelector 
interface implemented by all three.

I removed the refNodes stuff from querySelector, since all use cases for 
it are covered by find/findAll.

I defined the concept of a "relative selector" a custom grammar to 
handle this better.

I also started updating the draft to use Selectors 4 and DOM4 references 
and terminology.  Some DOM3 references still remain, but they'll be 
changed eventually.  This meant the removal of terms like "context node" 
in favour of "context object" defined in DOM4, among others.

The editor's draft is here.
