More generally, the Selectors spec should properly define the model of 
the document selectors are matched against.

The simplest is probably to just use the DOM, as its already defined.

If we instead want to keep Selectors independent of anything and define 
a special-purpose document model, something (CSS ?) well also need to 
define the mapping with DOM, and clarify references to DOM node such as 
processing instructions in the definition of :empty
