[css3-selectors] Selector grammar: negation

The selector grammar [1] defines a simple_selector_sequence as follows:

simple_selector_sequence 
  : [ type_selector | universal ]? 
    [ HASH | class | attrib | pseudo_class | negation ]+ 
    | type_selector | universal ;

However, negation is nowhere defined in the grammar. Likewise, the
Selectors module prose does not mention a negative selector, only the
negation pseudo-class, which only takes a simple selector.

Is this an omission in the prose or a superfluous element in the grammar?

Does a selector like

  not( DIV[test] > P )

exist, representing all elements but P elements which have a parent DIV
with attribute test?
