1. I'm aware how selectors work in browsers and that that's different from  
how they'd work here, but there was no pushback from implementors given  
that this is something authors want to use. Note also that you don't get  
live collections.

2. I'm not convinced it should be a native data type in ECMAScript. It  
operates on the DOM which is not native to ECMAScript either. Having an  
object which implements some selector interface on which you can perform  
node tests seems like an interesting idea, but is currently outside the  
scope of this specification. If there is enough interest though it seems  
certainly we should look into.

3. Letting StaticNodeList inherit from Array and NodeList not is not an  
option. They have to be identical. Hopefully DOM Level 3 Core gets errata  
to say that only some object implementing the NodeList interface is live  
and not all objects implementing NodeList (well, it currently says  
something even vaguer if I remember correctly) so we can drop  
StaticNodeList and just define that the object is static.
