Where is the draft located that contains these changes? It seems you  
haven't updated the editor's copy which makes it hard for me to revew the

It's not a subset at all. Clarification is ok too, but I think the  
sentence is a distraction.

That may very well be so, but I don't understand what it's saying.

Leaving it as does not satisfy me as I think the sentence is unclear.

"Getting this attribute of an element must return the first Element child  
node of that element or null if there are no Element child nodes."

It would tell you upfront what the interface is and what members it  
introduces and provide pointers to the definitions of those members. I  
think that would make the draft more readable.

I don't understand why it's not in the editor's draft. Everything what  
this group does, including editorial work, is captured in public documents
