Sounds good to me. We have an informative "Not in this specification" 
section already, sounds like a good idea to add there.

I do think there has been some disagreement here. Anne has commented on 
reasons for returning null rather than throwing an exception, and I 
think I agree with him. I think the correct cause of action here is to 
raise an issue in the issue tracker.

Sounds fine to me. We could also include tests that first check if 
getElementById is implemented at all and if so tests that it functions 

The nice thing about testing getElementById is that it not only tests 
the DOM, but also tests that ID parsing works properly.

But this way a DOM L1 implementation still passes fine.
